New submission from Pablo Galindo Salgado <pablog...@gmail.com>:
When evaluating a frame object, it is possible to exit the execution with some variables in the stack. The frame deallocator (frame_dealloc) only cleans the stack if f_stacktop is not NULL, but this only happens for generators and when trace functions are set. The eval loop does this cleanup already if an exception is being raised, but not if a RETURN_VALUE is set. In the PyconUS sprints, Dino and I have been working on this and we have decided that the cleanest approach is shared the same goto label with the path for exception handling, effectively cleaning up ---------- components: Interpreter Core messages: 341891 nosy: dino.viehland, pablogsal priority: normal severity: normal status: open title: Frame stack is not cleaned after execution is finished with return versions: Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36851> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
