> I think it is technically not possible. Neither PyDict_Next() nor Py_INCREF() mutate the dict, call the user code or release GIL. If it could be possible, we would have a potential writing out of a buffer here.

When I read PyDict_Next(), I'm thinking at the Python level which can execute arbitrary code. But it seems like you are right: the exact C implementation of PyDict_Next() doesn't seem to modify the dictionary.

PR 9009 seems safe.
