As a result, Rust stable ABI packages are now crashing on assertions, e.g. from `uv`'s `cargo test`:\n\n```\n          5 │+python3: Objects/unicodeobject.c:15018: intern_common: Assertion `_Py_IsImmortal(r)' failed.\n          6 │+python3: Objects/unicodeobject.c:15018: intern_common: Assertion `_Py_IsImmortal(r)' failed.\n```\n\nBackporting 281ffb60cc194c4eefee3e112888251abd1a749a seems to fix the immediate issue but I haven't checked for more regressions.\n\n### CPython versions tested on:\n\n3.12\n\n### Operating systems tested on:\n\nLinux\n\n### Output from running 'python -VV' on the command line:\n\nPython 3.12.7 (main, Oct  1 2024, 21:49:30) [GCC 14.2.1 20240921]","author":{"url":"https://github.com/mgorny","@type":"Person","name":"mgorny"},"datePublished":"2024-10-02T11:30:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/124887/cpython/issues/124887"}
