This indicates a bug in `ruff`. If you could open an issue at:
https://github.com/astral-sh/ruff/issues/new?title=%5BInfinite%20loop%5D
...quoting the contents of `PY_FILE_TEST_1909706726.py`, the rule codes ANN201, D100, D103, F841, along with the `pyproject.toml` settings and executed command, we'd be very appreciative!

Contributor guide
Research direction
Reproduce the failure with the attached PY_FILE_TEST_1909706726.py and the command `ruff *.py --select ALL --no-cache`, using rules ANN201, D100, D103, and F841. Inspect the convergence handling involved in these diagnostics; done means the command completes without the 100-iteration error while still reporting the expected lint findings.
