Thanks.  Is this reproducible?  If so, can you show a recipe,
preferably starting from "emacs -Q"?

FWIW, I looked at the code, and I cannot understand how this could
happen.  The cause of the crash is that 'face' is NULL, so face->font
segfaults.  But 'face' is obtained from 'face_id', which is zero,
i.e. it's the default face:

>        glyph = {ch = 36, face_id = 0}

And init_iterator, which called produce_special_glyphs, makes sure the
basic faces, including the default face, are recomputed just before
the call to produce_special_glyphs:

  if (FRAME_FACE_CACHE (it->f) == NULL)
    init_frame_faces (it->f);
  if (FRAME_FACE_CACHE (it->f)->used == 0)
    recompute_basic_faces (it->f);

And recompute_basic_faces aborts if it is unsuccessful in recomputing
the basic faces, one of which is the default face.  Which didn't
happen here.  So how this could happen is a mystery to me; I'm
probably missing something.

It crashes some times but I'd like to say that this is the first crash in
this month.

So, I have no idea how to reproduce, frankly speaking I just hasn't found
running emacs and discovered .core

The only clue that I have that I was switched to different virtual screen
and emacs was on not seen one.

Additionally, inside .xsession-errors I do have:

  0xbf72627f9a1 <XSetWMNormalHints+0x2fd71> at emacs
  0xbf72625a8ee <XSetWMNormalHints+0xacbe> at emacs

  Segmentation fault (core dumped)

This is indeed NULL:

  (gdb) up 9
  #9  0x00000bf72613ced7 in produce_special_glyphs (it=0x723f0516cf78, what=<optimized out>) at xdisp.c:31605
  31605   xdisp.c: No such file or directory.
  (gdb) p it
  $1 = (struct it *) 0x723f0516cf78
  (gdb) p it->f
  $2 = (struct frame *) 0xbf99e5ccba8
  (gdb) p it->f->face_cache
  $3 = (struct face_cache *) 0xbf9945600f0
  (gdb) p *it->f->face_cache
  $4 = {buckets = 0xbf9e196d000, f = 0xbf99e5ccba8, faces_by_id = 0xbf93c9b3000, size = 168, used = 0, menu_face_changed_p = false}
  (gdb) p it->f->face_cache->faces_by_id
  $5 = (struct face **) 0xbf93c9b3000
  (gdb) p it->f->face_cache->faces_by_id[0]
  $7 = (struct face *) 0x0
  (gdb) p it->face_id
  $8 = 0
  (gdb)

so, I also dig a bit. I see that faces_by_id is enlarged as:

  /* Maybe enlarge C->faces_by_id.  */
  if (i == c->used)
    {
      if (c->used == c->size)
	c->faces_by_id = xpalloc (c->faces_by_id, &c->size, 1, MAX_FACE_ID,
				  sizeof *c->faces_by_id);
      c->used++;
    }

here, it's trust value from xpalloc, and inside I see that it uses xrealloc
which has this logc:

  if (!val)
    memory_full (size);
  MALLOC_PROBE (size);
  return val;

so, if val is NULL it calls memory_full and if it doesn't crash, it returns
NULL which not always fails as I understand it.

Does it make sense?

Too bad.  But quite expected, unfortunately.

That "used = 0" means the face cache is empty.  And I don't understand
how that could happen in this scenario, given that init_iterator makes
sure that if the cache is empty, the basic faces are recomputed (which
refills the cache with the basic faces).

Yes, but memory_full signals an error, which (a) you should have seen,
and (b) it prevents the rest of the code from being executed, because
it throws to top-level.  Thus, for all practical purposes the return
value of xmalloc does not matter if the memory could not be allocated.
So I don't believe this is what happened to you, even if we assume
that you have indeed ran out of memory (which in itself is quite
improbably on modern systems).

This isn't that large machine which has 16Gb ram, and I use default OpenBSD
limits which is:

  ~ $ ulimit -a
  time(cpu-seconds)    unlimited
  file(blocks)         unlimited
  coredump(blocks)     unlimited
  data(kbytes)         134217728
  stack(kbytes)        4096
  lockedmem(kbytes)    87381
  memory(kbytes)       15959444
  nofiles(descriptors) 512
  processes            256
  ~ $ 

thus, emacs instance which had crashed had run magit, markdown-mode and a
few other heavy things for couple of hours at least.

Additionally, I use 1Gb of RAM for /tmp, at time of crash it had run VM
which uses 5Gb, and over of it Chrome which consumes some memory.

So, I really think that it migth be tin on available memory.

But I haven't got any proof of that.

Anyway, I preserve the core, and if something additional is required, feel
free to ask.

The printed offsets from XSetWMNormalHints are so large that the
function in these frames cannot possibly be our XSetWMNormalHints
replacement, sorry.

Indeed, and GDB confirms that:

(gdb) p XSetWMNormalHints+0x2fd71
$7 = (void (*)(Display *, Window, XSizeHints *)) 0xbf72627f9a1 <emacs_backtrace+289>

(gdb) p XSetWMNormalHints+0x2fa97
$9 = (void (*)(Display *, Window, XSizeHints *)) 0xbf72627f6c7
(gdb)

Also, OpenBSD quite agressive in term of ASLR (address space layout
randomization), I doubt that it has to do with this, but I feel that it
worth to point. Does it ring any bell?

If you mean that ASLR could cause the problem, then I doubt that.
Almost all of the platforms supported by Emacs use ASLR nowadays.

bug#71712: 29.3; Crash on OpenBSD

[Kirill A. Korinsky]

I had upgraded to 29.4, and it had crashed one more time.

This time the crash had happened when I make a commit into large git
repository via magit.

I write commits message in new frame, and after pressing c c to open a frame
to write commit message, I had switched to another virtual desktop.

When I've switched back, I hadn't find emacs, but .core was here with the
same stack trace.

Inside magit's commit message buffere I use markdown mode.

The way to find the culprit in these cases is to run the recipe with a
watchpoint on the frame cache's 'used' count, and see which code
causes it to be zeroed.  Usually, it is some crazy Lisp run from one
of the hooks which we so graciously offer for grabs.  The tricky part
is to find that code and/or the recipe which could be used to
reproduce the problem at will, which I understand you don't have...

Well, I don't have any reproducer, indeed.

I may attach debuger and add watch point, but the best that I can share is
stacktrace when and if it happen.

There's also the "reverse execution" in GDB.  You could set a
breakpoint where it segfaults, with the condition that face == 0, and
when that breaks, do reverse-step until you get to the place where the
frame's face_cache is emptied (cache->used == 0); then produce a
backtrace, including xbacktrace, and hopefully we will see the
culprit.

I tried to attach GDB to running process, or start a new emacs under GDB.

Both attemt leads to massive amount of SIGSTOP signals, and if I switch
handler to nostop, I stop to get it, but resulted emacs is unresponsible.

I've rebuild emacs with

  --enable-checking='yes,glyphs' --enable-check-lisp-object-type \
    CFLAGS='-O0 -g3'

with hope that produced .core will be usefull.

??? Which software on your system issues SIGSTOPs?  And on what
occasions?  And why?

FWIW, I'm running Emacs under GDB a lot (albeit not on OpenBSD), and I
never see any SIGSTOP, unless I manually issue "kill -STOP" from the
shell prompt, or something similar.

Please show the GDB command you typed to change the handling of
SIGSTOP.

It will produce more useful core file, but as I explained, the problem
happens before the segfault, and the important question is: which code
between init_iterator and gui_produce_glyphs causes the frame's face
cache to be reset without immediately recomputing the basic faces.
This requires to examine the code _before_ the segfault location.

I was able to achive kernel panic, and in general gdb with emacs seems
broken. It was confirmed on OpenBSD side: https://marc.info/?l=openbsd-bugs&m=171948527801829&w=2

So, I run it with better core dump as the only option that I have.

Too bad.  How do people debug programs on OpenBSD, if GDB doesn't work
there?

> So, I run it with better core dump as the only option that I have.

Then I'm not sure we will be able to solve this bug, at least not
without a lot of printf-debugging and examining the possibly
voluminous output.

Here a tricky part: I have used GDB on OpenBSD more than once, which
includes attaching to a process on my mail servers when I hunt a bugs inside
it. And it works well.

Emacs is the first application which I can't debug on OpenBSD.

Probably here is third approach.

You had said that this is possible to achive it from elisp. This is
something new, and I use doomemacs as the base for my config. I haven't
touched mine config recently, but doomemacs were upgraded. The good news it
had one large upgrade with few dozen commits since April [1].

Probably I ma use the diff of changes to find potential bad call or
callback.

Not sure about OpenBSD, but FreeBSD switched to LLVM, i.e. clang and
lldb, a while ago. Do you have these?

I do, and attemt to use it looks like:

    ~ $ lldb /usr/local/bin/emacs 
    (lldb) target create "/usr/local/bin/emacs"
    Current executable set to '/usr/local/bin/emacs' (x86_64).
    (lldb) r
    Process 21865 launched: '/usr/local/bin/emacs' (x86_64)

and nothing had happened. I wait couple of minutes, but after I pres C-c it,
at least exits as:

    Process 21865 exited with status = -1 (0xffffffff) lost connection

anyway, it left the process:

    ~ $ ps aux | grep 21865 
    catap    21865  0.0  0.3 21200 42672 p2  TX      3:35PM    0:00.29 /usr/local/bin/emacs (emacs-29.4)

    ~ $ 

what means that debuging emacs doesn't work.

I've tried to debug xterm and it works like a charm via bot lldb and gdb.

Hi,

On OpenBSD, you need to use egdb from the gdb *package* to debug Emacs.
And it both works when Emacs is compiled with the in base clang compiler
or the gcc package.

Thanks for suggestion.

I've used egdb because gdb from the base system is quite old.

No, because I've used egdb already. Frankly speaking I can't do it via gdb,
lldb and egdb. It simple goes to a state which locks like a deadlock. I
can't kill emacs or used debuger, and the only way to ride off that
processes is reboot.

Futuremore, at least once I achived a kernel panic [1] by my attempt to
debug emacs. This was confirmed as bug by mpi@ [2] and claudio@ [3] who had
planned to improve it.

BTW, since I've rebuild emacs as suggested [4] I haven't faced any crash.

The URL in [4] is identical to [3], so did you make some copy/paste
mistake?  That URL doesn't suggest to rebuild Emacs.  I'd be
interested to know how you rebuilt it to make the crashes go away.

In any case, does this mean the problem is solved, and this bug can be
closed now?

Thanks.  So an unoptimized build doesn't crash.  My suggestion would
be to try a build with "-O1 -g3" and see if that works for you.

Crash was reported at emacs-29.3 from official release (not git tag), and
was observed on emacs-29.4.

I'll run debug build for few days more to confirm that it hasn't got any
crash, and will try -O1 after that.

So you are saying that the problem exists in Emacs 29, but not in
Emacs 31 (on the master branch of the Git repository)?

What about the emacs-30 release branch?

I hasn't encountered the issue with optimization and without.

Seems that this issue can be closed because without a way to reproduce it,
no way to fix it.
