I don't think this is a bug: there's still a reference to the `A` instance in `sys.exc_info()` (specifically, in the exception traceback) in this case, so that instance is still alive. If you add an `except: pass` clause to your `try / finally`, you should see that dereferencing the weakref gives `None` in the `finally` clause. ---------- nosy: +mark.dickinson _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45555> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
