So on cmath.exp, we've seen something like this before, on macOS. What was happening was that the C source contained matching `sin` and `cos` calls, and a compiler optimization replaced that pair of calls with a single call to C's cexp. And then cexp didn't handle the zero signs correctly. I don't have an issue reference to hand; all this is from (highly fallible) memory. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39396> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
