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.
