I think the problem is that whatever is weak-referenced by the weak ref (CField_Type or similar) is not on the gc list. Because is not on the gc list, handle_weakrefs (https://github.com/python/cpython/blob/master/Modules/gcmodule.c#L1090) is not acting correctly on the weakreferences, clearing them before the tp_clear calls and therefore producing the crash.
