I've encountered test failures involving UCS and refcounts targeting Windows and Linux. Invoking `cargo test --no-default-features --lib --tests`, one example of failure is here: https://github.com/clin1234/pyo3/actions/runs/12834317749/job/35791414368. The Python version used for testing 3.14 is 3.14.0a4.\n\nHowever, running the same command with Python 3.14.0a3 running on Fedora Rawhide locally, I have encountered no test failures whatsoever.\n\nAnd yes, I have pinged @davidhewitt on this matter.\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-133085\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/clin1234","@type":"Person","name":"clin1234"},"datePublished":"2025-01-18T03:46:15.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/128972/cpython/issues/128972"}
