--- Comment #5 from Thomas Betker <thomas.bet...@rohde-schwarz.com> 2012-01-31 16:25:02 UTC --- Okay, got it; thanks a lot for the ultra-quick reply! Wouldn't a diagnostic message be helpful here even if it is not required by the standard? After all, the resulting binaries won't work correctly. I also keep wondering why things do work when optimization is disabled, but I guess the compiler may do anything it pleases since the input is invalid.
