It seems highly likely this is related to #26110 which optimizes method calls by avoiding the creation of bound methods in certain circumstances, and/or the follow-up #29263. Side-note: bound_method = functools.partial(method, self) is not how you create real bound methods. The correct approach (that makes a bound method identical to what the interpreter makes when necessary) for your use case is: bound_method = types.MethodType(method, self) ---------- nosy: +josh.r _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36650> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
