Any other information I can provide to be of assistance?

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?

Building with the latest version of the repository seems to fix things:

Or at the very least, I now get a different panic:

Shall I raise a separate issue for this error?

Thanks
