Can you provide the log for the configure and make commands?

The multiflavor tests seem to be running since we can see the expected
count.  However, ERROR probably means that the test crashes.  Since the
`got count' is zero, I think it might have crashed in test_mf_memb().

Here this time, we got two PASSes then an ERROR on the third test, which
is again on test_mf_memb().  So everything is pointing toward
test_mf_memb().  If this is the case, I suspect that if you run the
regression tests with `make regtest' you will have PASS on everything
except test_*_membarrier_* which will have ERROR.
