MeshInstance added as child nodes for CollisionObject debug shapes can be invalidated while deleting the collision object (child nodes are deleted first), which caused accesses to invalid memory in shape_owner_remove_shape that lead to random crashes. Also optimized accesses to shapes to avoid copy-on-write on each iteration.
