Running emacs --fg-daemon under gdb, and TTY emacs, with glyph debug
enabled. Using my full .emacs, which includes things like (setq
garbage-collection-messages t).
I reproduced this 2 times:
1. I opened 2 or 3 emacsclient (inside urxvt) and started resizing the
X window of one of them, and using it a bit (open org agenda). I admit
I used weird X window sizes that created a 1x1 terminal, but this
still worked. After some time playing with the X window size (but
without opening/closing X windows), this assert failed.
I was using urxvt with no customizations (i.e. I was seeing a scroll
bar etc.). In this case I used icewm (non-tiled window manager) with
no customizations.
See BT1 below.
2. I just ran emacs --fg-daemon inside gdb, and I opened my first TTY
frame, in a normal window of normal size; nothing weird (no 1x1 frames
etc). It immediately crashed; this never happened before. I'm using
wmii, urxvt (many customizations), and a command like urxvt -e
emacsclient '-nw' '-e' '(dired "~")' &
See BT2 below.
Maybe it's because of trying the display the "Garbage
collecting...done" message in a small window? (BT1) or in window which
isn't fully initialized yet? (BT2)

Thanks, but these backtraces are not enough, because they don't
explain why was emacs_abort called. We need to see all the values
involved in this condition:
if (curX (tty) == FrameCols (tty))
{
if (!MagicWrap (tty) || curY (tty) >= FrameRows (tty) - 1) <<<<<<<<<<<
emacs_abort ();

These were the variables just before emacs_abort, and (abort==1) when aborting.
At point cmcheckmagic, ¿abort? 0. MagicWrap 1, curY 0, vs. 3 - 1. Now
tty has 3 rows, 14 cols
At point cmcheckmagic, ¿abort? 0. MagicWrap 1, curY 1, vs. 3 - 1. Now
tty has 3 rows, 14 cols
At point cmcheckmagic, ¿abort? 1. MagicWrap 1, curY 3, vs. 3 - 1. Now
tty has 3 rows, 14 cols
I got them by adding:
fprintf(stderr, "At point cmcheckmagic, ¿abort? %d. MagicWrap %d, curY
%d, vs. %d - 1. Now tty has %d rows, %d cols\n",
(!MagicWrap (tty) || curY (tty) >= FrameRows (tty) - 1),
MagicWrap(tty), curY(tty), FrameRows(tty),
FrameRows(tty), FrameCols(tty));
I forgot curX, which is:
(gdb) p curX(tty)
$1 = 14
To reproduce this I had to try many random operations. The last thing
I did was increasing the size of an X window showing dired, from very
small (1 line, ~10 cols to 3x14); this works well most of the time but
this time this happened.

While playing with resizing the urxvt terminal size (X window), I
found other bugs where Emacs doesn't know the real size of the
terminal, or becomes unsynchronized with the actual terminal size.
This may cause many of the other bugs I've seen (things in the style
of: the GC message wants to use 2 minibuffer lines because it thinks
there are 2 lines, but actually there's just 1, etc.).
The two resizing bugs I found (but I don't have time to research them
in detail yet) are:
- if the X terminal has 4 visible rows, FrameRows(tty) reports 4. If
3, then 3. But if it has 2 or 1 rows, Emacs still sees 3. And editing
is garbled
- if I decrease the terminal size fast, e.g. 81→71→61→51→41→31→21→11→1
lines, often Emacs doesn't notice all changes, and it may still report
that FrameRows(tty) is e.g. 31 when it went further down to 1
(31→21→11→1)
- in addition there's a more complex refresh bug (not about resizing I
think), in which the next frame I focus after having killed a frame
won't be refreshed (e.g. I can resize the X window and it doesn't
notice, new sections appear black) until I press a key or move the
mouse. It's 100% reproducible but I need to research this better
because it involves window managers and X
However I didn't see a direct crash from these issues. But maybe a GC
message in some of these conditions can cause the alert.
I may report them as separate bugs but in a while; I'm reporting too
many TTY bugs and too fast; I need time for other things.
I also saw a new type of TTY+GC error (not sure if it's the same issue
as this bug):

So you are saying that the terminal lies to us? It has 3 rows, but
somehow wraps the cursor to the 4th row? What are the window and
frame dimensions at this point?

Please investigate what happens with our SIGWINCH handler (in
dispnew.c) in these cases.

I don't know enough to say whether the terminal is providing wrong numbers.
But it seems that the positions and terminal dimensions aren't wrong,
they're just outdated. They were right a moment ago (i.e. the terminal was
really as large as reported) but I was resizing the window during a slow
operation (GC) that was trying to display a message due to
garbage-collection-messages t, and it seems that the GC message is using
outdated information about the terminal size. That's my hypothesis.
I have reproduced this in a more drastic way, e.g. the cursor in line 14
and the terminal being 4.
At point cmcheckmagic, ¿abort? 1. MagicWrap 1, curY 13, vs. 4 - 1. Now tty
has 4 rows, 80 cols
> What are the window and
> frame dimensions at this point?
(I'm using the example mentioned above: 13, vs. 4 - 1).
The frame seems 4 lines 80 columns.
I'm not sure how to obtain the window dimensions from gdb, since there are
several fields. Here are two attempts to get it, but total_cols/total_lines
are 0 so it seems I'm not looking at the right fields.

Many of the backtraces I'm sending (more below) point to the same
issue: resizing the terminal while the GC messages are being displayed
can make the asserts fail.
Depending on the time I 'catch' it it shows an error or another in the
backtrace.
I still don't have a way to reproduce this, but the following recipe
seems to improve the chances:
(setq garbage-collection-messages t)
Then run some operation that clearly triggers GC. For instance I'm
using this formula (better ideas welcome):
(setq gc-cons-threshold 100000)
(cl-loop for i from 3000000 downto 1 do (+ 2.00 (+ 2.0 (+ 2.0 (+ 2.0
(+ 2.0 2.0))))))
While that operation is running (you'll repeatedly see "Garbage
collecting" "… done"), resize the terminal constantly until it
crashes.
But sometimes I can't reproduce it at all with this method!
And never could I in emacs -Q
But I'm getting tired of manually testing. I may have to automate the resizing.
Anyway this is a very rare bug which probably only happens when GC
messages are enabled, in TTY emacs, and while resizing the terminal.
An obvious workaround if this affects others is disabling
garbage-collection-messages, which seems buggy.
Maybe the problem is in message3_nolog.
Here's are two backtraces of two crashes in different points that I
didn't report yet. I suspect they are all this same bug because they
involve GC.

In the case mentioned above, in which: after killing a frame and resizing
another one, new sections appear black.
I reported it as bug #71343, since it's not related to GC like this bug.

I'm not sure I understand: is this related to this bug in some way?
Bug#71343 seems to describe a GUI frame (if not, what does the
window-manager have to do with it?). While here we are talking about
TTY frames, right? And killing frames is not involved in this bug
report, right? Or what am I missing?

That hypothesis needs to be explained. Which is why I asked to
investigate what happens when the SIGWINCH handler is called.

We determine the actual dimensions of the frame in the SIGWINCH
handler, and the new dimensions are recorded by the signal handler in
f->new_width and f->new_height, see change_frame_size_1.

It doesn't crash for me.

So maybe you could bisect your init files and find the
customization(s) which make the reproduction possible? Because I
cannot reproduce any of this here, no matter what I try.

This one (bug 71289) seems to be about crashes involving GC messages
and resizing the terminal.
I don't know the root cause; it could be some bug in the redisplay code.
I started thinking about other redisplay bugs and filed bug#71343, but
that one isn't related to this bug because it's not about GC. The
other 2 issues I mentioned may or not be related, I don't know.
In all reports I'm using TTY frames, i.e. Emacs compiled without X
support; it's not GUI frames. But I'm running them inside a urxvt
window in X with a window manager. I wanted a simpler and smaller
Emacs without any X support, but I still run it in X.
Killing frames is not involved or necessary for the current bug report (#71289).

AFAIR, almost all of the bugs you submitted have something to do with
GC messages, so the above doesn't help in any way to make this one
stand out, or am I confused?

So how is the window manager relevant here?

Bug 71343 has nothing to do with GC.
This one (bug 71289) does. I don't know what you mean by stand out; it
doesn't need to stand out.
But each bug is different, e.g.:
- 71176 was a bug about GC messages not working well when
opening+closing frames, in some conditions
- this one (71289) is about GC messages not working well when resizing
the terminal, in some conditions

Here (bug 71289) you need a window manager to resize the window (the X
window that is running emacsclient).
The particular window manager you use isn't important, in fact I saw
the same errors happen in wmii and icewm. Saying this is important,
because I was afraid that the problems could come from wmii (wmii
failing to communicate that an X window has been resized). But the
window manager isn't at fault in this bug 71289.

I tried but it took too long to evaluate each version, because I don't
have a formula to reproduce this. Sometimes I could crash it in
seconds, sometimes I couldn't in minutes.
I'll try to reproduce it in a faster way.

Please update from Git before trying anything else wrt this bug. I
installed a simple baind-aid that is intended to avoid problems with
frame dimensions while we have an unhandled SIGWINCH.

If this was while you only resized the terminal, how come a terminal
was deleted? Any idea what would cause this?

Thanks for the code.
With it (running on 799f78a92c6c31f4d181390523b83d036020ede1 with no
other changes), I still see the same types of crash that I already
reported: in tty_write_glyphs (see BT1 below) and in
build_frame_matrix_from_leaf_window (see BT2 below).
However they don't mention GC now.

I assume that it's t->name == NULL what tells you that a terminal was deleted.
But apparently this terminal wasn't fully deleted, because it's in the
terminal_list. If delete_terminal had run, shouldn't it have removed
it from the list?
So I don't know what happened. reference_count is still 1.
I might have actually tried to close an X window while I testing; I
can't remember. I'm collecting many backtraces and I wasn't very
careful in this one.
This backtrace may be a different bug; if you want I file it
separately. But since it happened during GC, it could also be due to
the same problems as this one (71289).
I don't know how to reproduce it.
Unless it clearly shows a defect, we can ignore this backtrace until
it happens again.

I'm trying to reproduce it again and again, and I can't find the way,
not even with my full .emacs. Yesterday it happened (I just posted
here BT1 and BT2) but today I can't, so I guess there are other
factors apart from GC and resizing.
I'll keep trying to use emacs normally and I guess then it should
happen when I least expect it.
For reference: I automated an automated continuous X window resizer:
EC=$(xdotool search --name '^\*E\* \.emacs') && echo $EC && while :;
do for height_px in `seq 275 -25 10`; do xdotool windowsize $EC
$((height_px+5)) $height_px; sleep 0.001; done; for height_px in
`seq 1 25 400`; do xdotool windowsize $EC $((height_px+5)) $height_px;
sleep 0.1; done; sleep 0.3 && done
And I keep trying to cause GC, with things like:
;; (cl-loop for i from 300000 downto 1 do (+ 2.00 (+ 2.0 (+ 2.0 (+ 2.0
(+ 2.0 2.0))))))
;; (cl-loop for j from 100 downto 1 do (progn (cl-loop for i from
30000 downto 1 do (+ 2.00 (+ 2.0 (+ 2.0 (+ 2.0 (+ 2.0 2.0))))))
(sit-for 1)))
;; (cl-loop for i from 3000000 downto 1 do (garbage-collect))
But this formula hasn't ever worked yet, so I guess I'm missing other factors.

So it is not exactly the same type of crash.
In what scenario does this happen now? IOW, what did you do to
trigger those crashes?
I'd like to ask you to run that scenario with a watchpoint on the
variable delayed_size_change, and the following two watchpoint
commands:
bt 5
continue
I hope the backtraces produced by this will explain who resets the
delayed_size_change flag, seemingly prematurely(?), and might suggest
ideas for a solution. (I have an idea already, but would like to see
some data to make sure the idea is solid.)
It is best to run GDB in a separate terminal for this experiment.
IOW, start Emacs, attach GDB to it from another terminal, say "set
height 0" to let GDB scroll the output freely, then set up the
watchpoint with the commands, and run Emacs with your recipe.
Thanks.

I decided to go with my idea anyway, so please update from Git before
trying next, and if the problem is still there, try answering my
questions above.
Thanks.

What's more important, kboard, keyboard_coding, and terminal_coding
are not NULL. Which means delete_terminal_internal was never run for
this terminal. I don't understand how that could happen, given the
backtrace you show.
I found some unsafe code in delete_terminal and installed a fix. I
cannot explain how that code could have caused the assertion violation
inside mark_terminals, but maybe it did.

I don't remember how the previous 2 crashes (BT1, BT2) happened. But I
just learnt to reproduce BT2 (in check_matrix_pointers), after 2 days
not being able to reproduce it.
The key to reproduce it to have 2 Emacs windows inside the frame:
1. Open emacs (no need for emacsclient) with -Q. No need to set
garbage-collection-messages to t
2. Do C-x 2 to have 2 windows, one above one below
3. Resize the X window to make it very small, (1 line or so)
4. It should immediately crash.

Thanks, that's a very good way to track changes. I'll do it when I can
reproduce the crash/assert. Right now it seems to work fine (opening a
new frame: false→true then immediately true→false).

I'm trying your new code (including the delete_terminals part), thanks.
I just posted a reproduction step for BT2, in another thread here.
I'll try to repeat the other backtraces.
I'm working on many crashes and redisplay bugs at the same time and
they're piling up, and it's getting messy, sorry.
I've seen a new redisplay issue but I can't pinpoint yet where did it
come from, or to which bug it's related.
In rare cases, not only the Emacs frame doesn't use the full size of
the terminal (after resizing the X window) (I consider this to be bug
71343), but also:
- it won't correct itself even after a keypress. I still see the black areas
- the text becomes garbled, e.g. the current line (the line I'm
editing) appears below the cursor, and the situation affects new
frames too, and the solution is to restart Emacs
I can handle it as part of 71343, which I'm still researching.

I see a different abort, for which I've now installed a fix. To try
to fix the above one, I need some additional data:
(gdb) frame 2
(gdb) p window_matrix->rows->glyphs[0]
(gdb) p frame_matrix->rows->glyphs[0]
(gdb) p frame_matrix->rows->glyphs[2]
(gdb) p window_matrix->nrows

Right now if I run the C-x 2 and resize scenario, I get this other
backtrace with build_frame_matrix_from_leaf_window, it's not the one
you requested (the one in check_matrix_pointers), but does it help?
This is with your latest patch.

When you do "C-x 2", does Emacs divide the root window horizontally or
vertically? Are the windows one above the other or are they side by
side?

One above the other.
It doesn't crash if I divide them left/right. I can even use the
auto-resizer loop and it doesn't crash, but as soon as I do C-x 2, it
crashes.

In an Emacs build with this patch, I can't see the minibuffer anymore,
also not while I type. Happens with -Q, with and without daemon.
I didn't have time to test this thoroughly or to find where it came from.

Sorry about that, late-night thinko. Should be fixed now.

It is, thanks.
The build_frame_matrix_from_leaf_window crash still happens.

That's another problem. There seems to be some disconnect, time-wise,
in reallocating frame matrices and sub-allocating window matrices from
the frame matrices, and the crash happens when the check is done
in-between those two.
This will need more work. Patches and relevant data are welcome.
