Seems to be fixed again.  Let's close this (reverting the pattern doesn't
reproduce it either).

I can confirm the runfail on barcelona (core-avx2 seems fine).  As said the
underlying issue was latent, you can easily see if compiling rhfuhf.F w/o
-Ofast fixes it.

The above suggested workaround to disable vectorization fixes it.

Thanks,

Not sure if it's the same issue, however I am seeing miscompare for 416.gamess
again with r241197.

Thanks,

The issue is latent again, keeping the bug open to chase the real issue
eventually when I have time to.
