Bug description:
doctest.DocTestFinder is now failing to collect examples from functions that are defined in C and then wrapped. It still works just fine with functions that are defined in C but that arenot wrapped.
This bug was introduced by#115440. It breaks doctests for Numpy ufuncs in pytest-doctestplus (seescientific-python/pytest-doctestplus#248).
I have placed reproducer code in this Gist:https://gist.github.com/lpsinger/65e59728555dc2096af88d394e2d4a6b. To reproduce, retrieve the code and run the following commands:
pip install -e .python test.pyThe script test.py fails with this error message:
