Ugh, none of these look expected.  Can you cut'n'paste the
OMP_PROC_BIND=... OMP_PLACES=...
line from before some of these errors and see if you can
reproduce it with running ./affinity-1.exe with those two env vars?
Can you strace | grep affinity it?
The == 8 to >= 8 change is already in the gomp-4_0-branch BTW.
