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.
