  "message": "bpo-44348: BaseException deallocator uses trashcan (GH-28190)\n\nThe deallocator function of the BaseException type now uses the\r\ntrashcan mecanism to prevent stack overflow. For example, when a\r\nRecursionError instance is raised, it can be linked to another\r\nRecursionError through the __context__ attribute or the __traceback__\r\nattribute, and then a chain of exceptions is created. When the chain\r\nis destroyed, nested deallocator function calls can crash with a\r\nstack overflow if the chain is too long compared to the available\r\nstack memory.",
