It seems latest Python 3 breaks testing?
I will try to reproduce in the weekend.

python-3.8 seems to fail the same. I ran tests with pytest (many python packages use pytest), is it a supported configuration? Looks like running the test file directly works without failures.

Good catch. Never used it before.
