Comment 7 for bug 926379

Crashing in mesa around here:

mesa-git-ubuntu/src/mesa/drivers/dri/i915/intel_context.c:
   /* Release the buffer storage now in case we have to return early
    * due to failure to allocate new storage.
    */
   if (buffer->attachment == __DRI_BUFFER_HIZ) {
      intel_miptree_release(&rb->mt->hiz_mt);
   } else {
      intel_miptree_release(&rb->mt);
   }

Guess it's a regression in mesa 8? Probably should go upstream; would be helpful to know steps to reproduce first though.
