           Version: 7.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

Archive with the source file(fortran), Makefile, compilation output and the
assembly output file

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
Intel(R) Xeon Phi(TM) CPU 7210 @ 1.30GHz

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