Hey! I'm sorry you're having issues. Unfortunately, I can't reproduce the problem you're having.

I have added your examples as tests, and they are passing in CI (bdd55e3).
I have also added MacOS to run in CI, and the new tests are passing on MacOS as well.

I also cannot reproduce when I run locally on Windows 11, with Rust 1.81 or Nightly, and with Python 3.12 or 3.13.

Does it happen every time you run it? Or does it sometimes succeed?
