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.
