3.12: Python/bytecodes.c:2995: _PyEval_EvalFrameDefault: Assertion method != NULL failed` in boto3 test suite #108487
Description
Crash report
CPython versions tested on:
3.12
Operating systems tested on:
Linux
Output from running 'python -VV' on the command line:
Python 3.12.0rc1+ (heads/3.12:09487a202f, Aug 25 2023, 15:57:40) [GCC 13.2.0]
What happened?
When CPython 3.12 is built with assertions enabled, the boto3 test suite crashes in tests/unit/test_session.py if it is run after a test from tests/functional/test_session.py. I can only reproduce this with Python 3.12, and I've tested as far as back as to 3.12.0b4. Pythons 3.11 and 3.10 work fine.
My reproducer so far:
git clone https://github.com/boto/boto3/ cd boto3 git checkout 1.28.34 pip install . pytest python -m pytest -s tests/functional/test_session.py::TestSession::test_can_access_region_property tests/unit/test_session.py::TestSession::test_arguments_not_required Error messages
