mesa crash report - xlockmore

Hi All

I've reported the issue to on [Xlock-develop] mail list first (http://calypso.tux.org/pipermail/xlock-develop/2011-October/000198.html) 
but was advised to raise it here.

On my machine when I run xlockmore it crashes every other day, see the stack trace attached.

My system:
Linux shdev05c 2.6.35.14-97.fc14.x86_64 #1 SMP Sat Sep 17 00:15:37 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
Fedora release 14 (Laughlin)

VGA compatible controller: Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02)

Works for me.  The backtrace looks like a GPU hang, though -- I'm guessing you have complaints in dmesg, in which case there are instructions at http://intellinuxgraphics.org/how_to_report_bug.html

(Also, be sure to use a current version of Mesa -- 7.9 is a year old at this point)

Closing for no feedback on checking for GPU hangs or updating Mesa.  The particular line of code where crash happened was deleted quite a while ago.
