The problem is that your program does not conform to
the Fortran 95 standard. A program(mer) is forbidden
to call an intrinsic procedure if it returns a result
that is outside the representable range of the return
trye. When you specified -pedantic, you declared that
the representable range is [-huge():huge()], which is
a strict interpretation of the model number representation
of an integer. NOT(1) is invalid with -pedantic.
