During the compilation of a program gfortran makes "internal compiler error:
Segmentation fault" It is jast normal fortran program, that can be compiled
without any problems with the older versions of gcc.
It hapens on
AMD Ryzen 7 1800X Eight-Core Processor
Intel(R) Xeon(R) CPU E5-2630 v4 @ 2.20GHz
it does not hapen on

If the option "-fno-unsafe-math-optimizations" is added, everything is fine, no
segmentation fault occurs.
