I think the issue here is that in assign_version_tag there's this code:

    if (type->tp_version_tag == 0) {
        // Wrap-around or just starting Python - clear the whole cache
        type_cache_clear(cache, 1);
        return 1;
    }

the return 1 is incorrect, it should be return 0 as a valid version tag hasn't been assigned.
