The fortran program, which does the infinite loop with compiler version 10.3.0
I wrote a function in gfortran-10.3.0, which computes the square root with the
heron iteration method. Without optimization the program is okay, but if I turn
on optimization, then it does an infinite loop. I use Kubuntu 20.04.
