STINNER Victor added the comment: Thanks Xiang Zhang. The fix is obvious and simple, but it wasn't easy to identify it ;-) I pushed the fix to Python 3.5 and default (3.6).
Python 2.7 doesn't crash, the bare "raise" statement raises the exception: TypeError('exceptions must be old-style classes or derived from BaseException, not NoneType',). I suggest to not touch Python 2.7 and close the issue. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27558> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
