After changes for auto-composition aware string-width (*),
emacs segfaults frequently on startup under macOS.
gdb 'bt full’ is attached:
emacs_crash-lisp_string_width-gdb_bt_full.txt
emacs_crash-lisp_string_width-macOS_report.txt
On my machine, crash occurrence frequency can be increased with
attached init.el. Unfortunately, I cannot reproduce the crash with
`--enable-checking='yes,glyphs' --enable-check-lisp-object-type`
configure options.
Sometimes emacs starts without crash, but font setting is corrupted
like the attached screenshot: after-lisp_string_width-autocmp.png
Regards,
—Naofumi

commit 85da7b57bc204c4cc6953156c1a9a4dc6e875541
Author: Eli Zaretskii <eliz@gnu.org>
Date: Wed May 26 20:08:47 2021 +0300
Make 'string-width' auto-composition aware
* src/composite.c (find_automatic_composition): Now extern.
(char_composable_p): Don't assume 'unicode-category-table' is
always available.
* src/composite.h (find_automatic_composition): Add prototype.
* src/character.c (lisp_string_width): Support automatic
compositions; call 'find_automatic_composition' when
'auto-composition-mode' is ON.

So it's some kind of invalid "symbol".

This seems to indicate Emacs is asking string-width to compute width
of a string that has 479 characters? How come we have such a long
string here?

What are the arguments to 'format' here?
(gdb) pp args[0]
(gdb) pp args[1]

What function is being called here, and with what arguments?
(gdb) pp fn
(gdb) pp arg1
(gdb) pp arg2
(gdb) pp arg3
The command 'pp' is defined in src/.gdbinit, you may need to source
that file before you could use the command.
Thanks.

Hi Eli,
I succeeded in getting more details by gdb ‘pp’ command.
`format’ call, leads to lisp_string_width crash, seems `tramp-password-prompt-regexp'.
Please look at the attached log and screenshot:
emacs_crash-lisp_string_width-gdb_bt_full-with-pp.txt.bz2
emacs_crash-lisp_string_width-gdb_bt_full-with-pp.png
It seems that this segfault depends on some delicate matter of
startup initialization timing.
This crash couldn’t be reproduced with full ${top_builddir}/src/.gdbinit settings,
so I copied ‘pp’ command definition to ${top_builddir}/.gdbinit then invoked
'gdb ${top_builddir}/src/emacs' like this:
```
[naofumi@hyperion emacs (master)]% pwd
/Users/naofumi/_git/git.sv.gnu.org/emacs
[naofumi@hyperion emacs (master)]%
[naofumi@hyperion emacs (master)]% cat ./.gdbinit
# Print out s-expressions
define pp
set $tmp = $arg0
set $output_debug = print_output_debug_flag
set print_output_debug_flag = 0
call safe_debug_print ($tmp)
set print_output_debug_flag = $output_debug
end
document pp
Print the argument as an emacs s-expression
Works only when an inferior emacs is executing.
end

Maybe. At least the user init file is processed during startup after
the window-system was fully initialized. The fontset you show in your
crashed session also looks fine to me. So I cannot explain why trying
to find font for an Arabic character could crash for you.
Therefore, I went ahead and disabled accounting for automatic
character compositions in 'format' and 'format-message'. Only
'string-width' tries to account for that. Please see if that solves
your problem.

This in itself is very strange, and probably indicates that there's
some memory-related problem somewhere. If the change I installed
solves your problem, I will try looking for such a problem.
Thanks.

No problem. I’ll try it.

Yes, very strange. It seems memory or cache related.
I have tried to get simple printf logs of crashed `lface’ Lisp_Object access via
lisp_gtring_width()/find_automatic_composition() and free_realized_face().
According to the attached logs, find_automatic_composition() could attempt to access
to deallocated `lface’ objects on startup under macOS.
It could be macOS-specific because I have not seen such segfault under linux.
## Patch for realize_face, free_realized_face printf logs

Except for this printf patch, there is no difference of execution environment
described in previous email.

commit 23ad0f0c5adbeda9a0bd346138e2950cb5e5a136
Author: Eli Zaretskii <eliz@gnu.org>
Date: Sun May 30 11:16:59 2021 +0300
Don't account for character compositions in 'format' and friends
'lisp_string_width' is called from 'format' and 'format-message',
which can be called both very early into Emacs initialization and in
other contexts where using the font backend is impossible or
undesirable. So this commit changes 'lisp_string_width' to try
accounting for automatic compositions only when explicitly requested,
and only 'string-width' does that; 'format' and 'format-message'
don't.
* src/character.c (lisp_string_width): Accept an additional
argument AUTO_COMP; attempt accounting for auto-compositions only
if that argument is non-zero. (Bug#48732)
* src/editfns.c (styled_format):
* src/character.c (Fstring_width): Callers of 'lisp_string_width'
adjusted.
------------------------------------------------------------------------
This workaround works fine. I think this issue can be closed.
Access to unrealized 'face->lface' Lisp_Object is not seen anymore
on startup, and no segfault happens with both simple reproducing
'tramp-syntax’ init.el and my daily-use more complicated init.el.
I comfirmed it on two intel macs which this segfault was observed:
- MacBook running the latest macOS 11.4
- Mac mini running macOS 10.14
At the same time, font corruption issue with some themes is also disappeared
as Pankaj said on emacs-devel list.
(After autocmp string-width commits, I had seen the font corruption
issue frequently with doom-tomorrow-night of doom-themes package.)

Thanks for testing.
I think the problem was in styled_format: it keeps C pointers to Lisp
string data around the call to lisp_string_width, which could cause
GC, which could relocate Lisp strings. But after the last change,
lisp_string_width as called from styled_format can no longer cause GC,
so that problem is gone. And there are other valid reasons why
'format' and 'format-message' are better without this feature, so I
think we will leave it at that.
