[Bug fortran/98701] I compiled a program with gfortran on Mac (Big Sur, version 11.1) and g77 on Windows 10. I get two very different results for identical input files with the results from the one compiled by gfortran being wrong.

I spent a good chunk of today to debug.  The culprit was two variables that had
not been set equal to 0.  I get the same results with g77 on Windows, GFortran
on Mac Big Sur, & AbsoftTools ( I downloaded a trial version to help me debug)
on Mac Big Sur

You guys are so helpful. I truly appreciate your time and.
