stacktrace from the crash
Reproduction steps:
enable sna & TearFree
start Xorg in gdb on an empty VT
start xterm on the new display (no window manager)
start glxgears from the xterm
use ctrl-c in the xterm to abort glxgears
continue relaunching and aborting glxgears until Xorg crashes.
I am attaching a couple of gdb generated stacktraces obtained using those
steps. The crash also occurs in a normal X session but I don't have a log for
that. Also it does not happen if TearFree is disabled.
This was observed while using the following versions:
xserver: 1.13.99.901
xf86-video-intel: 2.20.16-48-g52fd223
libdrm: 2.4.40-3-g0980633
$ uname -a
Linux namdle 3.8.0-rc1-namdle+ #1 SMP Fri Dec 21 22:46:59 EST 2012 x86_64
