umockdev's test suite now started to see this crash in current Ubuntu
jammy. Simple reproducer:
$ cat tests/xorg-dummy.conf
Section "Device"
Identifier "test"
Driver "dummy"
EndSection
$ Xorg -config tests/xorg-dummy.conf -logfile /tmp/log -once :5
Then, run at least one query on it, like this:
$ env DISPLAY=:5 xinput
Then pkill/kill or Control-C the Xorg process, and it will crash:
double free or corruption (!prev)

Title:
Xorg/Xwayland segfaults in OsLookupColor() from funlockfile() from
glamor_get_pixmap_texture() from glamor_create_gc()
Status in X.Org X server:
Fix Released
Status in xorg-server package in Ubuntu:
Confirmed
Status in xorg-server package in Fedora:
Won't Fix
Bug description:
Recently, my the xserver on my system has started randomly crashing
due to a segmentation fault. As far as I can tell, this segmentation
fault occurs as a result of libglamoregl encountering a
GL_OUT_OF_MEMORY error (see attached Xorg.log). I have had a hard time
reproducing this bug reliably, but it mostly happens when I have been
using Inkscape for a while.
This appears to be the same bug that has been reported here
https://bugs.freedesktop.org/show_bug.cgi?id=110500
https://bugs.freedesktop.org/show_bug.cgi?id=110714
In those bug reports, the usual recommendation is to switch from the
-modesetting video driver to the -nouveau video driver. By default,
Ubuntu is not configured in this way, so this bug probably needs to be
addressed in some other way.
My graphics card is listed as follows:
