I can reproduce it. It's not specific to OSX. It is specific to OMP-build (even running one thread) and also to vanilla SSE2:

Benchmarking: raw-sha256-ng, Raw SHA-256 [128/128 SSE4.1 instrinsics 4x]... (8xOMP) DONE
Raw:	19333K c/s real, 4750K c/s virtual

Benchmarking: raw-sha256-ng, Raw SHA-256 [128/128 XOP instrinsics 4x]... (8xOMP) DONE
Raw:    16891K c/s real, 2114K c/s virtual

Benchmarking: raw-sha256-ng, Raw SHA-256 [128/128 SSE2 instrinsics 4x]... (8xOMP) FAILED (get_hash[0](4))
