Actually, I have been thinking about this more and I cannot really trace how the bug could happen. We control the type allocation, but Py_tp_alloc controls the instance allocation and that can be anything, the current patch should not interfere with that.

Petr, do you have a reproducer? I tried to create a reproducer of a type that overrides Py_tp_alloc but not Py_tp_traverse (therefore it does not implement gc support) and I cannot make it crash.
