From: Leonardo Hernández <leohdz172 <at> proton.me> To: bug-gnu-emacs <at> gnu.org Subject: 29.0.91; PGTK Emacs crashes after clearing the clipboard Date: Sat, 20 May 2023 18:52:31 +0000
Hello, I have been having issues with crashes running Emacs with PGTK
on Wayland.
To reproduce, open `emacs -Q`, then copy whatever you want with <M-w> or
<C-w> and then copy another thing outside Emacs, for example, `wl-copy
<<< "Copied text"`, then Emacs crashes.

I have been testing and seems that this happens when
both `-O3` and `-march=native` exist in CFLAGS, if I turn `-O3`
into `-O2` or remove `-march=native` then it does not crashes.
This is most likely a bug in gcc rather than emacs, right?,
in case you required it, my gcc version is:
gcc (Gentoo Hardened 13.1.1_p20230513 p2) 13.1.1 20230513

If I'm not mistaken, what seems to be shown is that an invalid selection
event somehow ended up in the keyboard buffer, to be processed by
process_special_events. Possibly, one such event was processed earlier,
but not correctly removed from the keyboard buffer.
What is:
(gdb) p kbd_buffer[1344].sie
?

that produced the backtrace I replied to. Would you please show a

I suppose what this shows is that an invalid SELECTION_CLEAR_EVENT has
somehow found its way in to the keyboard buffer.
We need to narrow down the scope of the problem. If you comment out the
entirety of `process_special_events', does the crash still occur?

The crash does not happen when copying text from outside emacs,
however it crashes when pasting text killed from emacs,
for example, open `emacs -Q` kill some text and try to paste that
text outside emacs (just run `wl-paste`)

I did not apply the patch, instead I updated to 42052686752e399e778d33401dd621afbac0071d
which is basically the same patch. It still crashes (the same way I reported first).
