Sorry, I think I might have misinterpreted your post, because
I don't fully follow your logic here:

you showed you can reproduce the same issue on a different
system with a different BLAS implementation than either me or Lukas, 
and you conclude that the problem is Mac specific?

I probably am missing something, could you elaborate more?

BTW, it seems Lukas is using the reference BLAS implementation
while I am using ATLAS from MacPorts built with gcc4.7.
