New submission from STINNER Victor: "1L << 31" is undefined if long is 32 bits long. We should use unsigned long for PyTypeObject.tp_flags.
Attached patch implements this fix. I don't know if it breaks somehow the backward compatibility. See also issues #1621 and #7406. ---------- components: Interpreter Core files: unsigned_tp_flags.patch keywords: patch messages: 171574 nosy: ezio.melotti, haypo, mark.dickinson priority: normal severity: normal status: open title: tp_flags: Undefined behaviour with 32 bits long versions: Python 3.4 Added file: http://bugs.python.org/file27347/unsigned_tp_flags.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16086> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
