I can so far only produce this with magit[1], but I've attached the output
of "bt full" below.
1. Open up a diff in magit (e.g., M-x magit-status then RET on the first
line).
2. Press RET on an added line.
3. In the opened buffer, do M-: (setq display-line-numbers t)
4. C-x b RET
5. Press RET on the line again.
If I use (e)debug to try and trace the function call, then for whatever
reason it doesn't crash at step 5, but a call to `list-buffers' will
then crash. It also doesn't crash if I use (call-interactively
#'magit-diff-visit-file) rather than hitting RET, even though RET is
bound to `magit-diff-visit-file'.

It doesn't crash for me here. But since it's hardly repeatable for
you, I'm not surprised.

If you go to frame #3, in maybe_produce_line_number, and type
(gdb) pgrowx it->glyph_row
what does that produce? (You will need to source src/.gdbinit for the
pgrowx command to work.)
Btw, your recipe didn't quite work for me: the first step failed when
I pressed RET "on the first line" of the buffer presented by "M-x
magit-status" in the current release branch tip. It said there was
nothing to show about that line. I needed to find a suitable line
further down in the buffer. Am I missing something here? Can you
specify precise steps, assuming I know nothing about using Magit?
Thanks.

What about using the below recipe?

That's odd, since I believe unless there was a git error the first line
should start with "Head:" and pressing RET on it shows the commit at
HEAD. Maybe there's another situation where that's not the case.
Anyway, this might be more consistent:
1. emacs -Q in a directory containing a git repository
2. M-x package-initialize if needed
2. M-x magit-show-commit RET RET (should default to master)
This should bring up a *magit-revision buffer.
3. Move point to an added line (or any line in a hunk, under the @@
lines) and press RET
4. M-: (setq display-line-numbers t)
5. C-x b RET (should take you back to the *magit-revision buffer)
6. RET
Just to specify a commit, try M-x magit-show-commit RET 92045f45 RET in
an Emacs repo and press RET on the following line:
+@code{file-symlink-p}, @code{file-system-info}

It sounds like you've rediscovered bug#27668. Robert Pluim lost the
ability to reproduce it when we were close to catching the offending
code, but maybe you will be able to pick up where he left off? In a
nutshell, the glyph rows where display_line produces glyphs are not
cleared, so they still hold the glyphs produced by some previous code
in the display engine. The question is where should we add a call to
clear_glyph_matrix to force the glyph rows to be cleared at the
beginning of display_line.
I wrote instructions for a debugging session to find that out, see
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27668#89
Instead of "r -Q", type just "run" to run Emacs as usual, or even
attach to an already running Emacs with "gdb -p", set the breakpoint,
and type "continue. The "Inside Emacs" part will have to be replaced
with your recipe, up to and including step 5, and you should invoke
redraw-display just before hitting the final RET in step 6, the one
that triggers the assertion. After performing the GDB commands and
continuing Emacs, hit RET, and post the backtraces from every time the
watchpoint set by those GDB commands is hit. I hope we will then see
the offending code that needs to be fixed.
Let me know if you need me to rewrite the instructions to fit your
case exactly.

What if HEAD is a merge-commit? I think this is what I got when I
tried. Anyway, this is just a tangential issue.

You mean "C-u M-x magit-show-commit", right? Tried this as well,
still no assertion violation.
Thanks.
P.S. Btw, I'm debugging this in the emacs-26 branch, so perhaps so
should you, to avoid any irrelevant differences between what you and I
see. I tried reproducing the assertion violation in both branches,
and failed in both.

Okay, I've pasted the output below. 2 watchpoints triggered right after
M-x redraw-display, and I only get the third before the assertion.
After your recipe, you mention update_display and how it runs after
Emacs "redrawn the window to the glass", so it should be noted that the
assertion violated is triggered before the buffer with
display-line-numbers is displayed.

I believe it should still show the "Head:" line, but there's no hunks
that are displayed in the revision buffer. I tried reproducing by
pressing RET on a filename in its revision buffer and it also crashes.

If you want to force a completing-read for the commit, then yes. Too bad
you still can't reproduce it; every build I've configured with
"--enable-checking=yes,glyphs --enable-check-lisp-object-type
'CFLAGS=-O0 -g3'" crashes here.

Okay, the debugging done above is with an up-to-date emacs-26
branch.

Thanks, but I need a backtrace at each hit of the watchpoint. The GDB
session I posted defined commands to be executed at the watchpoint, so
such a backtrace should have been executed whenever the watchpoint
triggered. Those backtraces is what I need to determine where is the
enabled_p flag set, because one of those places is unexpected by the
code. It's probably the last, but given what you posted, I cannot
see where did the call to prepare_desired_row originated.
Thanks.

Sorry, it seems that "M-x gdb" doesn't show the output of the commands
for me (is that a bug?), even with "M-x gdb-many-windows". I had to try
gdb on the command line to get the following:

Maybe it's a bug, I will look into that later.

Hmm... now I'm confused. Your original backtrace with assertion
violation indicated that it happened with the same call-stack below
redisplay_window:

The only difference is the value of cursor_vpos (probably because you
hit RET on a different line or generally used a different commit?).
But if prepare_desired_row _does_ reset the enabled_p flag, then the
assertion violation could not have happened...
Perhaps try_window is called again, after the call which hit the
watchpoint? To see if that's the case, please run the session again,
but modify it as follows:
. do NOT define commands for the watchpoint
. when the watchpoint triggers the first 2 times, type "continue"
. when it triggers for the 3rd time, type these commands:
(gdb) break xdisp.c:17039
(gdb) commands
> p w->desired_matrix->rows->enabled_p
> end
(gdb) finish
(gdb) finish
(gdb) finish
(gdb) continue
Then please tell: (a) what was the return value of try_window, as
printed in response to the 3rd "finish" command, and (b) whether the
breakpoint set on line 17039 of xdisp.c triggers right after that. If
the breakpoint does trigger, please see if the value of the enabled_p
flag is printed as true or false.

I agree that it's unfortunate. If you prefer, we could instead try
investigating why it doesn't happen for me: maybe we will succeed in
finding a variation that does, and then I can debug it here.
Here are some reasons why my configuration could work differently:
. the default font/font size is different (although I did try 3
non-default font sizes as well)
. my Magit is not installed and is not byte-compiled, and neither
are its dependencies, dash.el and with-editor.el; instead, I load
Magit manually, using load-library, from the directory where I
downloaded the latest Magit snapshot, before typing the recipe
commands
Thanks.

Seems like some GDB bug or misfeature. I've asked a question about it
on the GDB list.

Yeah, I'm using a different commit, sorry.

The return value appears to be true. The breakpoint does trigger right
after, and enabled_p is also true:

I tried it with a different font(size), without byte-compilation, and
with a magit git snapshot -- all still crashed for me. Have you tried
using MELPA[1] to install magit? Maybe that would work.

OK, so we need to understand the path the code takes after try_window
returns the value 1. This means, after typing "finish" 3 times, type
"next", then continue pressing RET until redisplay_window returns. I
need to see the path through the code until we exit redisplay_window
to understand where to put the missing call to clear_glyph_matrix.
Also, please recompile Emacs because:

Thanks.

I'm not sure how will this help. I don't want to install Magit, I
just use it from a directory where I unzipped its snapshot. How using
MELPA would change that?

I'm not sure how either; MELPA was just on my mind since that's how I'm
using Magit's dependencies.

Thanks. I installed a change that should fix the problem, please try
the latest emacs-26 branch.
As to why this doesn't happen to me: for some reason, on your system,
when all the frame's windows have been redisplayed, their frame's
'redisplay' flag is set, and that causes redisplay_internal to
immediately redisplay all the windows again, see this part of your
transcript:
> 14320 if (!f_redisplay_flag && f->redisplay)
> (gdb)
> 14321 goto retry_frame;
On my system, the 'redisplay' flag stays reset, so this goto is
bypassed, and the problem doesn't happen. If you can afford one last
effort, please re-run the recipe with a watchpoint set on the frame's
'redisplay' flag, and show the backtraces from every one of the
watchpoint's hits, then perhaps I will know next time what else to try
to reproduce such cases.
Specifically, after invoking redraw-display, which causes GDB to kick
in, do this:

The conclusion is that it's a bug, so it will be fixed in a future
version of GDB. If you can patch and rebuild your GDB, a patch that
worked for me and that applies to GDB 8.0 is here:

Unfortunately, when I try to use XFRAME, I get:
No symbol "__builtin_assume_aligned" in current context.
I tried the following workaround, but no backtraces showed up:

OK, then you could use a slightly different way:
Thread 1 hit Breakpoint 3, Fredraw_display () at dispnew.c:3032
3032 FOR_EACH_FRAME (tail, frame)
(gdb) n
3033 if (FRAME_VISIBLE_P (XFRAME (frame)))
(gdb) p frame
$1 = XIL(0xa000000001b5e380)
(gdb) xframe
$2 = (struct frame *) 0x1b5e380 <dumped_data+4020672>
"emacs@HOME-C4E4A596F7"
(gdb) p $2->redisplay
$3 = true
(gdb) watch -l $2->redisplay
Hardware watchpoint 4: -location $2->redisplay
(gdb) commands
Type commands for breakpoint(s) 4, one per line.
End with a line saying just "end".
>bt
>continue
>end
(gdb) continue
(The "xframe" command is defined in src/.gdbinit, so if you are not
running GDB from the src directory, you will need to tell it to read
that file:
(gdb) source /path/to/emacs/src/.gdbinit

When I try this, I get a different frame pointer and a warning message
from GDB. So let's hope this workaround is incorrect ;-)
Thanks.

Thanks, this is what I suspected: the difference between our systems
is that your Emacs is built with GTK, and moving the thumb of the GTK
scroll bar marks the frame garbaged, which also sets its redisplay
flag.
So this mystery is now solved, and we can close the bug.
