Thanks for the explanation. Makes sense.

Do you have any idea what might have caused the regression?

Yes, I finally got into this habit, after repeatedly breaking libgomp tests
with my patches without noticing it.

I also tried to document how to do this at the bottom of this wiki page:

It took me a while to figure out how to actually run the Fortran subset of the
libgomp suite (which is not very well documented, or I'm too stupid to find
it).
