--- Comment #1 from kargl at gcc dot gnu.org ---
Why do you thing that you should not get an exception?
e = -400
e*e = 160000
-e*e = -160000
exp(-e*e) = exp(-160000) <-- This is going to underflow to zero.
You specifically asked gfortran to signal an exception if
underflow occurs with the -ffpe-trap=underflow option. The
underflow threshold occurs at x = -745 for exp(x).
