Title:
Xorg assert failure: malloc(): unaligned tcache chunk detected
Status in xorg-server package in Ubuntu:
New
Bug description:
This problem started last week when we upgraded to xserver-xorg-
core:amd64 2:21.1.4-2ubuntu1.7~22.04.9. The bug does not appear to be
in xserver-xorg-core:amd64 2:21.1.4-2ubuntu1.7~22.04.8. It is
happening on multiple desktops with once or twice daily frequency.
The symptom is an Xorg crash
#13 0x00007f988615c476 in __GI_raise (sig=sig@entry=6) at
../sysdeps/posix/raise.c:26
#14 0x00007f98861427f3 in __GI_abort () at ./stdlib/abort.c:79
#15 0x00007f98861a3676 in __libc_message (action=action@entry=do_abort,
fmt=fmt@entry=0x7f98862f5b77 "%s\n") at ../sysdeps/posix/libc_fatal.c:155
#16 0x00007f98861bacfc in malloc_printerr (str=str@entry=0x7f98862f8d20
"malloc(): unaligned tcache chunk detected") at ./malloc/malloc.c:5664
#17 0x00007f98861bf3dc in tcache_get (tc_idx=<optimized out>) at
./malloc/malloc.c:3195
#18 __GI___libc_malloc (bytes=64) at ./malloc/malloc.c:3313
This may be related to #2060354, but the stack trace is quite a bit
different.
Perhap this is caused by freeing memory and then continuing to use it?
