> Do you possibly have a testcase?
I am not sure to understand what you ask for.
The source for cptrf2.f90 has been attached to pr53340. I can provide a version
of rnflow without the proc cptrf2 or an archive with the rnflow.f90 source
split to one file per proc.
If you ask for a reduced test, it is much more difficult:
(1) the code is not mine and I don't know it well,
(2) optimizations may change for tiny details of the source layout.
