Crash report
What happened?
Starting with Python 3.13.0b2, importingfreezegun causes the interpreter to crash on exit. I was able to reduce it into the following ugly quasi-standalone snippet:
importasyncioimportdatetimefromtypingimportTypeclasstzutc(datetime.tzinfo):pass_EPOCHTZ=datetime.datetime(1970,1,1,tzinfo=tzutc())classFakeDateMeta(type):def__instancecheck__(self,obj):returnTrueclassFakeDate(datetime.date,metaclass=FakeDateMeta):passdefpickle_fake_date(datetime_)->Type[FakeDate]:# A pickle function for FakeDatereturnFakeDate
$ python -c 'import repro'python: Objects/typeobject.c:143: managed_static_type_index_get: Assertion `managed_static_type_index_is_set(self)' failed.Aborted (core dumped)I've been able to reproduce it with 3.13.0b2, tip of 3.13 branch and tip of main branch.
