@fabaff I tried to reproduce this with Python 3.12.3 on macOS 14.4.1. For me, all tests pass.

What platform are you using?

Does it keep failing if you try to use a clean "git clone"?

@fabaff Closing this for now as I am unable to reproduce it. If you have new information, post it here and I will reopen it.

@fabaff The entire build structure has been modernized (see #8). Possibly this fixes any issue you had.

I still test failures on x86_64 with Python 3.13
