BUG/PROBLEM REPORT / FEATURE REQUEST

Hello everyone, unfortunately I was not able to create a minor example. But we get segmentation faults with our test setup. Tests using the ZeitCmsTestCase which builds on a custom plone.testing.Layer run into this issue. Below is hopefully a trace that will help you.

@tseaver I don't fully understand what happened here, but I did notice:

Py_TPFLAGS_MANAGED_WEAKREF is included in BASETYPE_FLAGS, so it is enabled for some types that didn't use the explicit weakref list before.
According to https://docs.python.org/3/extending/newtypes.html#weakref-support, PyObject_ClearWeakRefs still needs to be called from tp_dealloc even when using Py_TPFLAGS_MANAGED_WEAKREF

Toward #323.

tseaver · 2024-09-05T21:08:01Z

@stollero I have made a change in PR #324 which might fix the issue -- can you test with that branch?

@stollero Thanks for checking. 7ca6275 updated the branch with another flail -- could you try reproducing again, please?

@tseaver no more segmentation faults. Runs without any errors. Thanks a lot for the swift response.

@stollero Wonderful news! Thanks so much for the report, and for being willing and able to help test the PR.
