test reflax-extfor failing on many gcc versions
The purpose of this issue is mostly FYI. I compiled the code without MPI and hit the following failure in test.
pw_relax - relax-extfor.in: **FAILED**.
Different sets of data extracted from benchmark and test.
Data only in benchmark: geom.

gcc 10.2 was good as our nightly runs.
gcc 11/12 all versions fail. gcc 13.1 fails but gcc 13.2 works. It seems to be a bug in gcc.
