Instantiating Python objects from C - segfault on `type(obj)`, `__class__` attribute missing

I’m looking in Objects/typeobject.c at slot_tp_call, this seems to be the implementation to execute the call, not the implementation for whatever tp_call’s default value is.

Yes, don’t look at slot_tp_call, look at tp_call.

It should be enough to call type->tp_new and then not call your type->tp_init and instead do the initialization in a different method that directly receives the file handle.
