The fix needs to go in gnuradio-core/src/lib/filters/assembly.h

On the macbook it's executing the !__ELF__ branch.
I suspect that there's some Mach magic required here.

Looking at some compiler generated assember and checking the
predefined preprocessor defines should lead to enlightenment.

Be sure to leave the old default branch  -- I think it handled COFF or
a.out -- and add a new check for whatever's right for OS/X.
