I've seen it multiple time in the rpi buildbot logs.  I expect it'll show up on some other bots as well but I haven't gone hunting.\n\n### CPython versions tested on:\n\n3.12\n\n### Operating systems tested on:\n\nLinux\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-114186\n* gh-114222\n* gh-114223\n* gh-114249\n* gh-114516\n* gh-114517\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/gpshead","@type":"Person","name":"gpshead"},"datePublished":"2023-12-16T04:12:47.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":9},"url":"https://github.com/113205/cpython/issues/113205"}
