Weston GDB Backtrace
wl_shm_pool_resize crashes weston if a wl_buffer from the pool is attached to a
surface and the new size is smaller.
It looks like weston is trying to access memory outside of the new pool size
because it was attached with the old size. Maybe there should be a check if the
pool associated with the buffer has changed.</pre>
