Read the hypot man page. hypot(infinity, v) = hypot(v, infinity) = +infinity for all v, including NaN. So one can get a non-NaN when an NaN is involved in a computation. For the task at hand, I think gfortran should be compatible with either g95 or Intel, and because g95 and gfortran already agree the decision is moot. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30694
