I understand from Paul Ganssle that this bug was found using Hypothesmith in my stdlib property tests (reported at https://github.com/Zac-HD/stdlib-property-tests/issues/14).

As discussed in https://github.com/we-like-parsers/cpython/issues/91 and https://pyfound.blogspot.com/2020/05/property-based-testing-for-python.html I'm keen to help out how I can, so if there's anything more specific than "write tools, write test, and wait" please let me know!

Best,
Zac
