This has been historically the source of many problems because it can trigger a GC run in points where the VM is in an inconsistent state. This includes critical points of the eval loop but also during complex object creation since the GC can run while creating sub-elements of the final result meanwhile the object is not fully initialized.\r\n\r\nTo improve the situation, we can schedule a GC run on object allocation but the GC will only run then on the eval breaker in a similar fashion we currently use to run signal handlers, do GIL switch and run pending callbacks.","author":{"url":"https://github.com/pablogsal","@type":"Person","name":"pablogsal"},"datePublished":"2022-10-05T18:09:20.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/97922/cpython/issues/97922"}
