The problem is actually in compile.c, in compiler_class(): Each compilation scope holds the name of the enclosing class (for __name mangling). In the case of nested classes, the inner scope is first initialized with the outer class name, then replaced with the inner class name. But a Py_XDECREF(c->u->u_private) is missing here... I will submit the correction in a few hours. -- Amaury Forgeot d'Arc _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
