Summary: Xorg 1.15.0 segfaults randomly in memset() from
intel_drv.so
QA Contact: intel-gfx-bugs at lists.freedesktop.org
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: marti at juffo.org
Hardware: x86-64 (AMD64)
Status: NEW
Version: unspecified
Component: Driver/intel
Product: xorg
I have experienced this bug a few times after upgrading to Xorg 1.15.0, but no
idea about the cause. Sometimes it happens when the computer is locked,
sometimes when I'm using it.
I'm using up-to-date Arch Linux testing: xorg 1.15.0, xf86-video-intel
2.99.907, kernel 3.12.6, mesa 10.0.1 Intel HD 4000 graphics on i5-3570K. Gnome
Shell 3.10.2.1 desktop.
I found another report of this on openSUSE forums:
http://forums.opensuse.org/english/get-technical-help-here/applications/492955-13-1-gnome-logs-out-itself.html
(down currently, but here's a Google cached copy:

)
I caught this in gdb, but unfortunatley Arch doesn't ship debug symbols, so gdb
"bt full" doesn't provide any more info. Full Xorg.0.log is attached.
