I just updated to the latest HEAD, so I assume I have the cube_1.out 
that you changed. If you look at the order of the results expected in 
cube.out and cube_1.out, they are different. So I don't think we have a 
problem with the code, we just need to fix the ordering in cube_1.out.

The same problem appears in cube_2.out -- is this used by any platform?
