The test i did worked fine on my X6 CPU, on bull's CPU, on GTX 570 and 
on Radeon HD 6770. Only failed on 7970.

I can create a version that compiles fine on 7970, but with some kind of 
strange behavior.
(i just selected this example because it shows that something is not good).

Now the situation (commited at 
https://github.com/claudioandre/magnum-jumbo):
