GDB trace
Description of problem:
firefox4 crashes in mesa-7.10 with kernel-2.6.37 with nouveau driver (but in
soft rastering code)
Soft rendering was forced by running firefox with another user that has no
access to /dev/dri/card0.
Version-Release number of selected component (if applicable):
Tested on Fedora with:
mesa-dri-drivers-7.10-0.18.fc15.x86_64
firefox-4.0-0.17.beta9.fc14.remi.x86_64
kernel-2.6.37-2.fc15.x86_64
This is mesa snapshot from 2011-01-07.
How reproducible:
Always
Steps to Reproduce:
1. Set 'layers.acceleration.force-enabled' to true and
'layers.acceleration.disabled' to false in firefox4 (using about:config)
2. restart firefox
3. firefox prints "failed to create drawable" thenl segfaults in mesa
Actual results:
Segfault
Expected results:
soft rasterizer should not make firefox segfault
Additional info:
