>Description:
I get the following crash in the X server on my i915 laptop whenever I
go to start compiz or the desktop effects in KDE4.

Program received signal SIGSEGV, Segmentation fault.

I'm using 9.0-CURRENT, with xorg-server-1.6.5_1,1 xf86-video-intel-2.7.1_1, libdrm-2.4.17, and dri-7.6.1,2.

>How-To-Repeat:
Install FreeBSD i386 on a machine with an i915 GPU, update to -CURRENT (sorry, never tested on 8.0-RELEASE), install compiz-fusion or KDE4, enable opengl compositing.
