Tim Peters <t...@python.org> added the comment:
Also basic: run hardware CPU and memory stress diagnostics, and/or try running the same thing on a different machine. Hardware isn't infallible, and can fail in nearly arbitrary ways. For example, perhaps a smidgen of silicon has gone flaky, so that one time in a billion bit 0 "leaks" into bit 1 in a register. That can effectively change the integer 1 to the integer 2. Is that likely? No. But a loop doing mutually inconsistent things to the variables it's changing is impossible ;-) ---------- nosy: +tim.peters _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37168> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
