But not C++ tests. I'll look at this on Monday.

Not surprising, but nonetheless had to be confirmed: the diff is bisected to the fvm-removal merge. Does not occur on ride. Running with 1 thread shows it is not related to OpenMP. -fp-model strict is being used, so it's not an FP issue.

Intel 17 and 18 both have the diffs. If I remove -xmic-avx512 -O3 and replace with -O2, the diffs go away. -O3, even on its own, has the diffs. -xmic-avx512 -O1 is OK, but with -O2 it is not.
