Yeah, I'm looking forward to see comparable bugs being closed as "cannot reproduce" by some of the jokers. I suppose that you all had a note scribbled on the margin of your copy of Arithmetica that this cannot happen with arrays of lengths seen in practice until 2038 or so. These guys found a bug that is subtler than what most of us have dealt with in a widely used piece of code originally developed by one of the smarter members of the python "community". I bow my head to them and say thank you. -- https://mail.python.org/mailman/listinfo/python-list
