I could not reproduce this at all. It is in theory possible that we do
cairo_surface_destroy on a stale pointer (to a surface that was already
destroyed), and that different Cairo libraries are more or less resistant
to this.

If changing texture triggers the crash, the suspect routine is
CreatePNGBoard in draw.c. Perhaps you could add a few printf statements
there, to see in the console whether it exits the routine after entering
it. If that would work OK, the crash could still be elsewhere in the
routine CreateAnyPieces which calls it. If not, we should add more printfs
to find the crash point by bisection.
