Skips cleanup of 8 owned refs. Reachable via `marshal.loads()` with crafted input.\n\n\n### CPython versions tested on:\n\nCPython main branch\n\n### Operating systems tested on:\n\n_No response_\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-148419\n* gh-149363\n* gh-149364\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/Wulian233","@type":"Person","name":"Wulian233"},"datePublished":"2026-04-12T02:23:35.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/148418/cpython/issues/148418"}
