Hi,

I built everything from git after your changes, and I now have a crash
in the xserver when launching compiz.
Configuration :
- Intel G33 chipset using the driver from git
(e04333a6352040bc883655d606923c912d005981)
- git mesa f9c6dfc4d12451c21f39f38b048758cbee5723cf + patch from
http://bugs.freedesktop.org/show_bug.cgi?id=9264 (to run compiz)
- xserver : 927757e1028f45f7fd94b9a2ab35567e0f34b2a8

Backtrace of the crash when launching compiz :
