Subject: 25.3; Core dump on GTK with -Q

[Message part 1 (text/plain, inline)]

After doing some commands in Emacs/GTK, emacs and my window manager
crashes and I get logged out.
As I write this I'm at `/bin/emacs -nw -Q`, because emacs crashed while
reporting bug.

I've reproduced it several times with the following commands:
1. `/bin/emacs -Q`
2. `C-h C-p` for PROBLEMS-buffer
3. `M-x org-mode` enable org-mode
4. Tab (`org-cycle`) on headline
5. Emacs and window manager hangs and emacs get core dump

But I have also had the crash when running:
1. `/bin/emacs -Q`
2. `M-x report-emacs-bug`
3. scroll down line by line with `C-n` to the bottom
4. scroll up line by line with `C-p`
5. When point was at the left parenthesis in the `Features` section same
crash.
Or:
1. `/bin/emacs -Q`
2. `M-x report-emacs-bug`
3. `C-x C-f emacs.bug` (File where I saved journalctl entry)
4. `C-x space` and scroll down with `C-n`
5. Somewhere in the middle of file the crash happened.

This started yesterday as I updated both Emacs, Kernel, X as well as
some other packages with `pacman -Syu`.

I have some other crashes from other programs in journalctl. The system
seems to be stable when not running emacs (or only `emacs -nw`).

Please let me know if you need journal or pacman logs.

Can you build Emacs with debug symbols, so we can get a more informative
backtrace?  Is it possible this is the same as Bug#30653 (which turned
out to be a mesa bug)?

Yes, you are probably right, I upgraded mesa today (17.3.5-1 -> 17.3.6-1)
and I can no longer reproduce this.

Do you still want me to build emacs with debug, and downgrade mesa to prove
it?

I'm happy with this result so we could close this bug.

No, I think upgrading is already enough proof.

I see Glenn has already closed and merged.
