I think this is wrong. It does not say anywhere but I'd expecttp_free to take a reference toPyObject (e.g.PyObject*), not a reference to reference to it (e.g. not aPyObject**).

Seems abandoned - requested changes not addressed.

Not abandoned, just very low priority. We have to fix these warnings eventually, they are extremely spammy and the non-copyability check is borderline useless right now. Either we fix things or we drop the analyzer until an official one is added.
