Failing jaro_winkler_similarity_longto on python 3.10 and 3.11 (Fedora 36 x86_64)

I get the following when running the python only test suite on Fedora with both python 3.10.5 and 3.11.0rc1:

Same issue here with Mageia cauldron and python 3.10.

I'd look for an issue with those platforms, I've confirmed tests are passing on four other platforms, including on Python 3.11rc2 which I just added to CI. Perhaps there are hints in the compiler output?

Going to close this out as tests are all passing on 3.10 and 3.11 for the various builds we support, feel free to reopen if there are reproducible failures that you can submit a test for.
