--- Comment #4 from Rimvydas (RJ) <rimvydas.jas at gmail dot com> ---
Interesting. I see failure even on online godbolt compiler x86-64 gfortran
(trunk) with -O2: "Killed - processing time exceeded"
Just rechecked on fresh arch linux with gcc 12.2.1 host:
$ ./gcc/gfortran -Bgcc/ -v -O2 -ftime-report -c hog.f90
