Stefan Krah added the comment: In theory we should set FENV_ACCESS whenever the control word is changed (C99):
"If part of a program tests floating-point status flags, sets floating-point control modes, or runs under non-default mode settings, but was translated with the state for the FENV_ACCESS pragma "off", the behavior is undefined." In practice gcc ignores the pragma, icc and cl.exe use it, not sure about clang. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24520> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
