I can't reproduce the miscompares - are these really the only flags you use?
Which local patches do you apply to gamess?  For me gamess just hangs (but
even before the patch - ah, PR53086).

I do see a _lot_ of generated memcpy/memmove calls, so bisecting those will be
hard.

I can reproduce it with -flto which avoids PR53086, but only with ref input.

Do you have a SPEC patch for PR53086?

Thx.
