Crash report
What happened?
Starting with Python 3.13.0b2, importing freezegun
causes the interpreter to crash on exit. I was able to reduce it into the following ugly quasi-standalone snippet:
import asyncio
import datetime
from typing import Type
class tzutc(datetime.tzinfo):
pass
_EPOCHTZ = datetime.datetime(1970, 1, 1, tzinfo=tzutc())
class FakeDateMeta(type):
def __instancecheck__(self, obj):
return True
class FakeDate(datetime.date, metaclass=FakeDateMeta):
pass
def pickle_fake_date(datetime_) -> Type[FakeDate]:
# A pickle function for FakeDate
return FakeDate
$ 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.
CPython versions tested on:
CPython main branch

Output from running 'python -VV' on the command line:
