Title:
  [945gm mesa] Segfault when using colorfilter plugin

Status in X.org xf86-video-intel:
  In Progress
Status in “xserver-xorg-video-intel” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: compiz

  when trying to use colorfilter, this is what happens:

  - I press the keyboard shortcut
  - Everything except the mouse freezes
  - About 5 seconds later compiz crashes

  When run in the terminal, i get this message:

  Mesa 7.4.1 implementation error: i915_program_error: Exceeded max ALU 
instructions
  Please report at bugzilla.freedesktop.org
  Segmentation fault

  I've never used colorfilter before, so I don't know if this is a
  regression or not.  I'm using Karmic. I'll do a backtrace later
  tonight.
