Hi.
I'm running a bleeding-edge build of emacs. Using packages from:
https://emacs.secretsauce.net/
Debian GNU/Linux. GTK+. Currently using a build from git as of
2024/07/09 (8e46f44ea0e). It is crashing periodically, with an unclear
cause.
This isn't a brand-new problem; I observed a similar crash with an earlier
build: 2024/04/30 (d24981d27ce). After that crash I upgraded, and I see
crashes still.
Anecdotally, the 2024/04/30 build has been very stable. Today I started
to debug a different issue: something about mu4e modeline updating is
signalling args-out-of-range. To debug this I'm tweaking functions like
(truncate-string-to-width), and re-evaluating them. This debugging isn't
very interesting, but something about it is causing emacs to crash, with
both builds.
I just made a core. I cannot xbacktrace because (I think) I'm looking at
a core, and not at a live process. If that would be helpful, I can
probably get that. And I see the crash every 20min maybe, while
debugging the mu4e modeline problem. Below is the backtrace. Hopefully
this speaks to somebody. Thanks!

If the above is false, then the call to emacs_abort after that if could not have possible been the one which caused the abort. The line number information in an optimized build could be inaccurate, so it is important to establish which condition caused the abort. > The backtrace is silent about the specific values of each of these, but > I can try to get them.

So when you say that "anecdotally, the 2024/04/30 build has been very stable", what exactly do you mean?

Thanks, but please always try to supply the information that explains the crash, not just the backtrace. (In this case, it's a deliberate abort, not a crash, but still.) That means look at the source code where GDB says the problem happens and print the values of the variables involved in the crash. In this case: > (gdb) bt full > #0 __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=6, no_tid=no_tid@entry=0) at ./nptl/pthread_kill.c:44 > tid = <optimized out> > ret = 0 > pd = <optimized out> > old_mask = { > __val = {0} > } > ret = <optimized out> > #1 0x00007fc68a4a6b7f in __pthread_kill_internal (signo=6, threadid=<optimized out>) at ./nptl/pthread_kill.c:78 > #2 0x00007fc68a4584e2 in __GI_raise (sig=sig@entry=6) at ../sysdeps/posix/raise.c:26 > ret = <optimized out> > #3 0x0000561d3dcb9798 in terminate_due_to_signal (sig=sig@entry=6, backtrace_limit=backtrace_limit@entry=40) at ./debian/build-x/src/emacs.c:469 > #4 0x0000561d3dcb9d4e in emacs_abort () at ./debian/build-x/src/sysdep.c:2391 > #5 0x0000561d3dcb6c34 in redisplay_window (window=<optimized out>, just_this_one_p=just_this_one_p@entry=false) at ./debian/build-x/src/xdisp.c:20086 The call to emacs_abort seems to be here: /* Some sanity checks. */ CHECK_WINDOW_END (w); if (Z == Z_BYTE && CHARPOS (opoint) != BYTEPOS (opoint)) emacs_abort (); <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Now, your "bt full" doesn't help to understand what went wrong because GDB is unable to find the values of many variables: > w = 0x561d6bcb2bc8 > f = <optimized out> > buffer = <optimized out> > old = <optimized out> > lpoint = { > charpos = <optimized out>, > bytepos = <optimized out> > } > opoint = { > charpos = <optimized out>, > bytepos = <optimized out> > } Still, at least Z and Z_BYTE should be available; what are their values? And regarding opoint, look back in the code a small ways to where it was defined: SET_TEXT_POS (opoint, PT, PT_BYTE); If you look up the definition of SET_TEXT_POS, you will see: /* Set character position of POS to CHARPOS, byte position to BYTEPOS. */ #define SET_TEXT_POS(POS, CHARPOS, BYTEPOS) \ ((POS).charpos = (CHARPOS), (POS).bytepos = BYTEPOS) which means opoint takes its character position from PT and its byte position from PT_BYTE. So if you print the values of PT and PT_BYTE, we will know the ("optimized-out") values of opoint.charpos and opoint.bytepos, and will probably be able to understand why we aborted. IOW: (gdb) frame 5 (gdb) print Z (gdb) print Z_BYTE (gdb) print PT (gdb) pt PT_BYTE (The "frame 5" command is to get to the callstack frame where we call emacs_abort, shown as #5 at the right edge of the backtrace line.) If GDB says it doesn't know about these variables with up-cased names, like Z and PT_BYTE, it means your Emacs was built without macro information (the -g3 compiler option), and you will need to type the macro definitions instead. For example (from buffer.h): #define PT (current_buffer->pt + 0) So instead of "print PT" you will need to say "print current_buffer->pt". And similarly with other variables above. Next question is: what buffer did Emacs try to display? To answer that, print the name of the buffer that is current in this place in the code: (gdb) print current_buffer->name_ (gdb) xstring If GDB says it doesn't know what "xstring" is, type: (gdb) source /path/to/emacs/src/.gdbinit and then repeat the above 2 commands. Once you know which buffer was being displayed, try to describe the text that was in it, if you can. (If you cannot, I can give instructions how to find it out using GDB commands.)

I've been using the April build for many months, and haven't seen any crashing at all until today. Today I tried to debug the mu4e modeline problem, and saw it crash. Then I updated to the latest build (2024/07/09) hoping it would be fixed, and kept seeing crashing, as I continued to debug. So whatever the problem is, it started in April or earlier. Here're some notes about the mu4e problem that looks correlated with this crash, maybe. I'm hazy on the details here, so there's no bug report yet, but I've at least pinpointed the mechanism. truncate-string-to-width() in international/mule-util.el has (condition-case nil (while (< column end-column) (setq last-column column last-idx idx ch (aref str idx) column (+ column (char-width ch)) idx (1+ idx))) (args-out-of-range (setq idx str-len))) The intent was that we might have idx >= length(str), so (aref str idx) would signal args-out-of-range, and the condition-case would catch it. But this is reliably not happening under some (probably over-specified) conditions: - mu4e is running, with multiple mail contexts; it shows the selected context in its modeline, which eventually calls truncate-string-to-width() - I have some remote file opened with TRAMP - I run (shell-command) from the remote buffer In at least this scenario, args-out-of-range errors from the above (aref ...) are uncaught (100% of the time with my config), and appear in the *Messages* buffer. I was debugging this by tweaking and re-evaluating my local copy of truncate-string-to-width() and other related functions in the *scratch* buffer, while looking at the *Messages* buffer in another window. Will get back to this in a sec. Here's what I see in the core dump: (gdb) p current_thread->m_current_buffer->text->z $22 = 32192 (gdb) p current_thread->m_current_buffer->text->z_byte $23 = 32178 (gdb) p current_thread->m_current_buffer->pt $24 = 32192 (gdb) p current_thread->m_current_buffer->pt_byte $25 = 32178 So that tells me that the failing condition isn't the one gdb flagged, but the one immediately after: if (BYTEPOS (opoint) < CHARPOS (opoint)) emacs_abort (); The compiler optimizations could be responsible for the discrepancy. Am I understanding correctly that this check makes sure that BYTEPOS >= CHARPOS, which must always be true because sizeof(emacs character) is always >= 1byte? The buffer name: (gdb) p current_thread->m_current_buffer->name_ $26 = XIL(0x7fc685b24c1c) (gdb) xstring $27 = (struct Lisp_String *) 0x7fc685b24c18 "*Messages*" I confirm that the text is our own text: (gdb) p ¤t_thread->m_current_buffer->own_text $43 = (struct buffer_text *) 0x7fc685a107e0 (gdb) p current_thread->m_current_buffer->text $44 = (struct buffer_text *) 0x7fc685a107e0 The full structure: (gdb) p current_thread->m_current_buffer->own_text $45 = { beg = 0x561d7100f800 ... z = 32192, z_byte = 32178, gpt = 32191, gpt_byte = 32177, gap_size = 1313, modiff = 69879, chars_modiff = 69879, save_modiff = 1, overlay_modiff = 10, compact = 53392, beg_unchanged = 0, end_unchanged = 0, unchanged_modified = 69373, overlay_unchanged_modified = 6, intervals = 0x0, markers = 0x561d6da79bc0, inhibit_shrinking = false, redisplay = true } Looks like gpt and gpt_byte have a similar inconsistency as z and zbyte. Looking at the definitions in buffer.h, I guess the above means that the gap starts at gpt_byte-1 = 32176 Let's look at the last bit of the buffer: (gdb) printf "%.2200s\n", ¤t_thread->m_current_buffer->text->beg[30000] share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-mime-parts.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-modeline.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-notification.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-obsolete.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-org.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-pkg.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-query-items.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-search.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-server.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-speedbar.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-thread.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-update.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-vars.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-view.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-window.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e.el Checking /usr/share/emacs/site-lisp/elpa/mu4e-1.12.5/mu4e-actions.el 0 matching files marked Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range "" 0) [3 times] Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range #("<fastmail>" 1 9 (face mu4e-context-face help-echo "mu4e context: fastmail")) 10) Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range "" 0) [5 times] Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range #("<fastmail>" 1 9 (face mu4e-context-face help-echo "mu4e context: fastmail")) 10) QuitError during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range "" 0) Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range "" 0) [2 times] Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range #("<fastmail>" 1 9 (face mu4e-context-face help-echo "mu4e context: fastmail")) 10) Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range "" 0) [5 times] This particular print ("Error during redisplay") happens (I think) when I removed the (condition-case ...) stuff above to let the (aref ...) fail. I wouldn't crash most of the time. Also I'm not at all confident that this is the only scenario where it crashed, but maybe. Let's look just at the last little bit, to count the bytes: (gdb) printf "%.200s\n", ¤t_thread->m_current_buffer->text->beg[32000] mail>" 1 9 (face mu4e-context-face help-echo "mu4e context: fastmail")) 10) Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range "" 0) [5 times] I asked for at most 200 bytes (up to byte 32200). I got exactly 176 bytes, so the text ends where the gap supposedly begins. That makes sense. Let's look a bit past the end, INTO the gap (gdb) x /3cb ¤t_thread->m_current_buffer->text->beg[32176] 0x561d710175b0: 0 '\000' 0 '\000' 114 'r' So we have two trailing \0 bytes. Past them: (gdb) printf "%.200s\n", ¤t_thread->m_current_buffer->text->beg[32178] rror during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range "" 0) Theory: there's a race condition between error handling that ends up writing to *Messages* and the logic that aggregates duplicated messages into things like [5 times]. People usually don't have lots of errors happening, and they usually don't stare at the *Messages* buffer, so this is easily missed. Anything more you would suggest? I saw the crashing once every 20min maybe, so reproducing it is probably possible, but not very quick and easy. Does it make sense to try to fix the (condition-case) problem first, since that's easily reproducible? Thank you ^ permalink raw reply [flat|nested] 21+ messages in thread

The question is: which code modified Z and GPT without updating the corresponding _BYTE variables, or the other way around? > Let's look just at the last little bit, to count the bytes: > > (gdb) printf "%.200s\n", ¤t_thread->m_current_buffer->text->beg[32000] > mail>" 1 9 (face mu4e-context-face help-echo "mu4e context: fastmail")) 10) > Error during redisplay: (eval (mu4e--modeline-string) t) signaled (args-out-of-range "" 0) [5 times] > > I asked for at most 200 bytes (up to byte 32200).

My suggestion is to run Emacs under GDB with a watchpoint on Z_BYTE, conditioned on the situation that Z_BYTE and Z are not equal. This watchpoint needs to be defined when the current buffer is the *Messages* buffer. One way of doing that is as follows: $ gdb ./emacs ... (gdb) break Frecenter (gdb) run After Emacs starts, type "C-x b *Messages* RET" to display *Messages* in a window, then type C-l to trigger the Frecenter breakpoint, and when GDB kicks in, type at the GDB prompt as follows: (gdb) n (gdb) n (gdb) p buf (gdb) watch $1->text->z_byte if $1->text->z_byte != $1->text->z This relies on the fact that our code always changes Z_BYTE _after_ the suitable change to Z. The only exception to this rule that I found is in insdel.c:del_range_2, where we do it in the opposite order. So for the above to work, you need to edit that function and transpose the line of code which modify Z_BYTE with the one which modifies Z. Then rebuild Emacs and use the resulting binary to debug this with the above watchpoint. > Theory: there's a race condition between error handling that ends up > writing to *Messages* and the logic that aggregates duplicated messages > into things like [5 times]. I don't see how this could happen, for two reasons: . emacs is a single-threaded program, so how can two pieces of code that run in the same thread produce a race condition? . in this particular case, both writing to *Messages* and aggregation of identical messages happen in the same function, one after the other; see xdisp.c:message_dolog. > I saw the crashing once every 20min maybe, so reproducing it is probably > possible, but not very quick and easy.

After some flailing I was able to make it crash with rr, so now I can see EVERYTHING. rr is truly a miracle, and figuring this out without it would have been impossible. I walked around the rr trace, and I clearly see the crashing mechanism. I don't dare fix it myself, but hopefully one of you will be able to, without a lot of trouble. The buggy function is message_dolog(): https://github.com/dkogan/emacs-snapshot/blob/439ec471961/src/xdisp.c#L12041 On line 12075 we save the current point as a marker (i.e. both the byte and char positions): oldpoint = message_dolog_marker1; set_marker_restricted_both (oldpoint, Qnil, PT, PT_BYTE); In the failing sequence I had some non-ascii characters, so PT_BYTE would be ahead of PT (by either 4 or 8 bytes). This difference is recorded into oldpoint. Then on line 12177 we check if we're exceeding message-log-max, and if so, delete some stuff from the *Messages*. if (FIXNATP (Vmessage_log_max)) { scan_newline (Z, Z_BYTE, BEG, BEG_BYTE, -XFIXNAT (Vmessage_log_max) - 1, false); del_range_both (BEG, BEG_BYTE, PT, PT_BYTE, false); } In the failing sequence we delete some of the non-ascii characters. So the byte-char offset changes: it was 4 or 8 bytes, and it becomes 0 or 4 bytes. At this point we're still correct. But very shortly after this, on line 12205 we restore the oldpoint into the current point. Since we just deleted stuff from the BEGINNING of the buffer, the oldpoint doesn't point to the same thing as before. Restoring it directly is wrong, but this normally doesn't cause crashes. The thing that causes crashing is that sometimes the byte-char offset in oldpoint is no longer correct, and we fail the consistency checks in redisplay_window(). OK. If more investigating is needed, I still have the rr trace, and can pull it up again. But I think we're clear on what's happening, and hopefully no more digging is required.

I'm confused by the last part of your description. The code which resets point to 'oldpoint' is this: if (point_at_end) TEMP_SET_PT_BOTH (Z, Z_BYTE); else /* We can't do Fgoto_char (oldpoint) because it will run some Lisp code. */ TEMP_SET_PT_BOTH (marker_position (oldpoint), marker_byte_position (oldpoint)); IOW, it uses 'oldpoint', which is a marker, not a simple number. It was initialized like this: oldpoint = message_dolog_marker1; set_marker_restricted_both (oldpoint, Qnil, PT, PT_BYTE); Since 'oldpoint' is a marker, it should have been moved by del_range_both so that it still points to the same text. Moreover, the char <-> byte correspondence was not supposed to be disrupted by that. So I think something else is at work here. Can you show the data you collected during the rr session? Specifically, what are the character and byte positions of 'oldpoint' before the call to del_range_both, how many characters and bytes were deleted by del_range_both, and what are the character and byte position of 'oldpoint' when we call TEMP_SET_PT_BOTH in the snippet I show above? One possibility is that the value of 'oldpoint' gets overwritten somehow between the place it is set and the place it is used to restore point. But in that case we need to find the code which overwrites it. ^ permalink raw reply [flat|nested] 21+ messages in thread

Moreover, > the char <-> byte correspondence was not supposed to be disrupted by > that. That is excellent to know! I'm not super familiar with the internals of emacs, so I don't know what is supposed to be handled, and might have jumped to the conclusion. Let's look again. I'm at a different cycle from before, but it still fails from a message-log-max truncation. - I'm at the top of redisplay_window() that has a crashing state, right after a redisplay_window() cycle with a non-crashing state. The crashing state has z_byte-z = 8 but pt_byte-pt = 12. Both are at the end of the buffer, and 8 is the correct value. - I run backwards until the truncation in message_dolog(): if (FIXNATP (Vmessage_log_max)) { scan_newline (Z, Z_BYTE, BEG, BEG_BYTE, -XFIXNAT (Vmessage_log_max) - 1, false); del_range_both (BEG, BEG_BYTE, PT, PT_BYTE, false); } Right after this both z_byte-z=8 (correct) and the point is at the beginning. This is correct, and the truncation itself didn't break anything. Note: this was (eventually) called from redisplay_window(), in the display_mode_lines() call in xdisp.c:20941 - Then we restore the oldpoint; what I suggested was the problem previously: if (point_at_end) TEMP_SET_PT_BOTH (Z, Z_BYTE); else /* We can't do Fgoto_char (oldpoint) because it will run some Lisp code. */ TEMP_SET_PT_BOTH (marker_position (oldpoint), marker_byte_position (oldpoint)); After that, both z_byte-z and pt_byte-pt are 8. This is correct. - Then we do this, in redisplay_window() in xdisp.c:21908 /* Restore current_buffer and value of point in it. The window update may have changed the buffer, so first make sure `opoint' is still valid (Bug#6177). */ if (CHARPOS (opoint) < BEGV) TEMP_SET_PT_BOTH (BEGV, BEGV_BYTE); else if (CHARPOS (opoint) > ZV) TEMP_SET_PT_BOTH (Z, Z_BYTE); else TEMP_SET_PT_BOTH (CHARPOS (opoint), BYTEPOS (opoint)); We pick the "else" branch. The end result is the exact failing state we hit on the next pass through redisplay_window(). This sounds like a different flavor of what I described yesterday. So in summary: in a redisplay_window() call: - We set the opoint on line 20064. This is a text_pos, NOT a marker. So it wouldn't be updated due to the buffer changing. - On line 20941 we call display_mode_lines() which eventually deletes lines at the start of *Messages* and moves the point. - On line 21908 we restore the opoint, saved prior to the lines being deleted, and no longer valid Does this sequence sound more reasonable to you? The description from the previous email made sense to me yesterday, but maybe I was too sleep-deprived to tell for certain. Looking through yesterday's gdb session, I don't see the smoking gun anymore. Thanks much! ^ permalink raw reply [flat|nested] 21+ messages in thread

The *Messages* buffer is displayed in a window, which is redisplayed, and the display engine calls redisplay_window for it. . redisplay_window records the original position of point in the *Messages* buffer, then calls display_mode_lines, as it does for any window whose mode line needs to be redrawn for some reason . somewhere inside display_mode_lines, we call message_dolog, most probably because the mode-line format calls :eval, which signals an error . message_dolog adds some text to *Messages* and removes some other text from it, which invalidates the position of point recorded at the beginning of redisplay_window . redisplay_window then uses invalid value of point (including its byte position, which no longer corresponds to the character position) to set point, and that opens the gates of hell Is that correct? If so, this puzzle has the following pieces: . *Messages* is displayed and includes non-ASCII text . mode-line-format that signals an error when the window showing *Messages* is redisplayed . the size of *Messages* buffer and its contents are such that moving point to the value recorded at entry to redisplay_window produces a mismatch between PT and PT_BYTE If all of the above happen, we are toast. Right? Can you verify that the above theory is true? For example does CHARS_MODIFF value of the buffer after display_mode_lines returns differ from its value before the call? ^ permalink raw reply [flat|nested] 21+ messages in thread

I ran the april build of emacs for months with no issues, and only saw the crashes when trying to debug the *Messages* problem tickled by mu4e. So I doubt somebody else could readily reproduce the crash. In fact, so far, I haven't been able to reproduce it either, with the watchpoint enabled. But while debugging earlier, I saw it crash maybe 4 times within a few hours, so it's definitely an extant issue. For the record: $ dpkg -l mu4e ii mu4e 1.12.5-1 ^ permalink raw reply [flat|nested] 21+ messages in thread
