When running {{pytest}} on projects using {{pyarrow==0.14.0}} on Linux, I am getting segmentation faults, but interestingly _only_ when run via {{pytest-runner}}

This works (i.e. {{pytest}} directly):
{code:java}
$ pytest

However, this does not work, ending in a segmentation fault, even though the tests pass:
{code:java}
$ python setup.py pytest

I have observed this behaviour on my machine running natively, and also via docker.
