Subject: [Bug 37253] New: SIGSEGV in dri2FlushFrontBuffer/MakeContextCurrent
Date: Mon, 16 May 2011 06:46:14 -0700 (PDT) [thread overview]
Message-ID: <bug-37253-502@http.bugs.freedesktop.org/> (raw)
https://bugs.freedesktop.org/show_bug.cgi?id=37253
Summary: SIGSEGV in dri2FlushFrontBuffer/MakeContextCurrent
Product: Mesa
Version: unspecified
Platform: Other
URL: https://bugzilla.mozilla.org/show_bug.cgi?id=624935
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/Gallium/r600
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: bjacob@mozilla.com
This is the bug forcing us to blacklist Gallium in Firefox 6+.
Steps to reproduce:
0. This has been confirmed with Mesa 7.10.2, Gallium 0.4, and both R300 and
R600 but seems device-independent. I didn't find the proper category for
general Gallium bugs.
1. Grab a Nightly of Firefox:
http://nightly.mozilla.org/
2. Run it; If you're already using Firefox, you may want to do:
./path/to/firefox -no-remote -P
3. Make sure that WebGL is enabled (a bug in parsing version strings makes it
unintentionally blacklist some systems). Go to about:config, set
webgl.force-enabled=true if needed. You can go to about:support to check WebGL
status.
4. Go to http://people.mozilla.com/~sicking/webgl/ray.html
Actual results: segfault

I discussed this with Corbin Simpson
(https://bugzilla.mozilla.org/show_bug.cgi?id=624935#c6) who told me it was a
known Gallium bug, been discussed on the mailing list already:
