I wrote a small library to add thumbnails to dired here:
https://github.com/jojojames/media-thumbnail
When scrolling through images at a fast rate. (I hold down the key to go to the next line for example.),
emacs eventually crashes.
The behavior can also be seen with image-dired though I didn't test an emacs -Q for it.
https://www.gnu.org/software/emacs/manual/html_node/emacs/Image_002dDired.html
I can reproduce more reliably with my library due to its rapid fire calls to create-image (maybe?).
# Emacs -Q
(require 'package)
(add-to-list 'package-archives '("melpa" . "https://melpa.org/packages/"))
(package-initialize)
(package-refresh-contents)
;; $ git clone https://github.com/jojojames/media-thumbnail
;; (load "/Users/james/.emacs.d/packages/emacs_28/straight/repos/media-thumbnail/media-thumbnail.el")
(load "where-media-thumbnail-is-located/media-thumbnail.el")
(require 'media-thumbnail)
(add-hook 'dired-mode-hook 'media-thumbnail-dired-mode)
M-x dired # directory with a lot of images to scroll through
C-n until emacs crashes.
- # of images in directory can range in the hundreds.
- happens consistently when scrolling through hundreds of images, though not every time

Please compile Emacs with debug information and without optimizations,
then run it under a debugger, and when it crashes, please post the
full backtrace from the debugger, including the Lisp backtrace
(produced by GDB automatically if you source the .gdbinit file that
comes with Emacs).
Also, you didn't post the information about your build that is
normally collected by "M-x report-emacs-bug"; please post that, it's
important for the analysis of the possible reasons.
Thanks.

Crash/hang takes a lot longer to reproduce (need to scroll thousands of images) in gdb.
Not sure if I correctly added the debug symbols to the build, doesn't seem like it from the trace.

Ouch, macOS! You may need to use lldb, then, not GDB. And that will
make the job of finding the problem harder.

No, there are no symbols (or at least GDB couldn't find them). But I
don't think you were in the right thread when you did that. The Emacs
main thread is always thread 1, not 42 or some other number. So
always say "thread 1" before "bt full".
Did the SIGBUS thing happen when you did the image-scrolling thing
that causes crashes?

Unrelated to the crash but...
Not sure why this happens, but emacs 29 throws this error upon start up.
Any tips on debugging this?
Error (use-package): evil/:catch: Symbol’s value as variable is void: ‹\213 (It’s one full letter, not actually “\213”)

<function called from gdb>
The program being debugged was signaled while in a function called from GDB.
GDB remains in the frame where the signal was received.
To change this behavior use "set unwindonsignal on".
Evaluation of the expression containing the function
(backtrace_top) will be abandoned.
When the function is done executing, GDB will silently stop.

I believe so, but not sure.

Thread 44 doesn't look like our thread. If it stopped due to
EXC_BAD_ACCESS, then I don't know what to say about this.
Thread 1, which is the main Lisp thread, seems to be inside the Apple

So again, I don't see what that has to do with Emacs.
OTOH, redisplay works on macOS very differently from other platforms,
so maybe we are somehow causing this?

* bug#57267: 28.1; emacs crashes when loading too many images

To: james; +Cc: 57267, Eli Zaretskii
This could be heap corruption, I think.
Can you please build Emacs with ASAN? Something like:
git clean -xdf
./autogen.sh
./configure CFLAGS="-g -O0 -fsanitize=address -fno-omit-frame-pointer" \
LDFLAGS="-fsanitize=address -fno-omit-frame-pointer"
make
Everything above in the root of your Git worktree.
Then start Emacs like this:
cd src
lldb emacs
run
and do what you did to make it crash. If it's a heap corruption, and
ASAN can detect it, it will break into LLDB at that point. Then please
print backtraces and so on, as Eli said.

Too bad, that means ASAN didn't find a problem before the bad access happens.

Emacs' thread (#1) is displaying an image when thread #17 crashes.

That's a select for some reason, doing nothing.

That's the culprit, but I have no real idea what this thread is for.
One of the few things I could find on the web is
https://www.zerodayinitiative.com/advisories/ZDI-20-1182/ (a zero-day
vulnerability) which indicates that AppleVPA has something to do with
JPEG parsing.
Could it be that one or more jpegs of yours is invalid in some way?
Maybe you could check this with the 'jpeginfo' utitlity. I've never
used it myself, because I don't have a use for it, but from what I read,
it might be able to detect at least some error cases. Maybe it's worth
trying.
Another idea might be to try and install an external jpeg library
(libjpeg I presume), and configure Emacs to use it. Alas, this doesn't
seem to work on my M1 Mac, but maybe it does on your x86_64 system.
In any case, this doesn't look like a problem to me that is caused by
Emacs.

I don't quite understand. I've seen to open errors in your log. Are
you saying that these happen because you started Emacs from src this
time? FWIW, I don't see differences when starting one or the other.

Do you think that would lead to a crash every time? My crashes are very inconsistent.

Can you point me to some documentation for that?

time? FWIW, I don't see differences when starting one or the other.
They were separate issues.
1. 2022-08-19 10:09:53.301888-0400 emacs[92880:17395371] fopen failed for data file: errno = 2 (No such file or directory) (hmnn?)
^ Just recently saw that in the logs after applying your suggestions.
2. Before (your suggestions), I did this to run emacs:
>> gdb/lldb ../nextstep/Emacs.app/Contents/MacOS/Emacs
After, it crashed on startup every time, so I did instead:
>> gdb/llb emacs
This is what I get with the Emacs.app binary: (upon startup)
src/ $ lldb ../nextstep/Emacs.app/Contents/MacOS/Emacs

I can't really answer that question because, as a starter, I don't even
know what AppleVPA is doing when it crashes, and there's no way to find
out, AFAIK. In general, with multi-threading, ASLR, and whatnot, things
tend to not behave consistently quite frequently, at least in my
experience.
I'd personally give jpeginfo a try. It's cheap. Just 'brew install'
it.

I can't find documentation for this. I guess I only "know" about this
because I added it in 1998, according to the ChangeLog, which must be a
lie :-).
Anyways. On my system, I just did 'brew install libjpeg' and then
'./configure'. The file config.log showed that configure was trying to
use libjpeg, but didn't like it for some reason I don't remember.
BTW, Homebrew also has other jpeg libs ('brew search jpeg' and so on),
but I didn't try them all. As I mentioned, I don't do much with images
myself.
Maybe it's also worth asking an help-gnu-emacs, if this doesn't work.
Or someone reading this knows more about this topic.

Ok, that's a relative path, so I think it expects to be started with
current directory being nextstep/Emacs.app.
