should use uintptr_t instead of size_t for pointer size

        return Z_OBJ_P(new_object);

    }

    static bitem * fetch_bnode_object_data(zend_object *obj) {

        return (bitem *)(*((size_t *)((char *)obj - sizeof(size_t))));

        return (bitem *)(*((uintptr_t *)((char *)obj - sizeof(uintptr_t))));

    }
