Fortran source file
The reduced code snippet has been working fine for a long time
gcc-6 up to gcc-9.1 but is broken know with 9.2 and 9.2.1.
The problem is reproducable on Darwin and Linux. It does compile
fine with intel-14 up to intel-19, pgi-17 up to pgi-19, nag 6.0 up to nag-6.2
cray ftn 8.4 to 8.7, and latest NEC Fortran.
