{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Missing error checks in `_PyEval_MatchClass`","articleBody":"Several places in `_PyEval_MatchClass` call `PyList_Append` without checking the return value (e.g., https://github.com/python/cpython/blob/fc2cb86d210555d509debaeefd370d5331cd9d93/Python/ceval.c#L509C13-L509C26).

It will only fail if we're out of memory or if we passed a non-list, so it's unlikely to come up in practice, but we should still check for errors.\r\n\r\ncc @brandtbucher for pattern matching\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-110238\n* gh-110511\n* gh-110512\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/JelleZijlstra","@type":"Person","name":"JelleZijlstra"},"datePublished":"2023-10-02T20:02:08.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/110237/cpython/issues/110237"}
