Problem description

pytest pandas fails at 22% with Windows fatal exception: stack overflow in test_inference.py line 131. According to the test file, the offending code is expected to raise a RecursionError.

Curiously, the following test runs green: pytest pandas/tests/dtypes/test_inference.py

Expected Output

When I run pytest pandas on the master branch (like I did), I expect the entire test suite to run green.

Output of pd.show_versions()

pd.show_versions()
Traceback (most recent call last):

  File "<ipython-input-3-3d232a07e144>", line 1, in <module>

@joooeey would you mind checking to see if you still have this issue (or if any other windows users can reproduce?)

[joooeey]

I'll have a look at it on the weekend.

[joooeey]

I'm not sure how to run the test suite.

This is what I get:

Is there anything else I need to do to run the tests?

Looks like this issue hasn't had much activity where other windows user were able to replicate the same behavior. Closing, but happy to reopen if we get a reproducer.
