In that case it's a wrong code bug. With -fno-range-check you've told the compiler to produce +Infinity rather than an overflow error. Instead, it takes it upon itself to produce something other than what the source says [which is log(y), not log(some expression that may or may not be called y)]. -- terry at chem dot gu dot se changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |terry at chem dot gu dot se http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34230
