--- Comment #6 from martin.schlipf at damnthespam dot com ---
Sorry, if that has not been clear enough. I already know how to work around
this issue. You can simply check the error flag [if (ierr /=3D 0) return].

What I do not understand is why gfortran removes the call to the first func=
tion
when I switch on the optimization.=
