[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 compiled with the suggested options (below) and now the code gives the same
result as g77.

-fcheck=all -ffpe-trap=zero,invalid

Things look good now!

Sorry for starting this bug report prematurely, and many thanks for your
help!!!
