%%%The problem is the "Add shader" node. Select it and hit Ctrl+X, then render with the cpu.%%%

%%%can not actually reproduce the issue here, probably this worth double-checking using fresh builds from builder.blender.org.

Brecht, can you please keep an eye on this?%%%

%%%Reconfirmed with 2.64 RC1, GPU (CUDA) and CPU render are different. %%%

%%%Same here with the build r50990,

The problem concerned the nested "mixshader" node, I removed the effect and replace it by another trick, it now works%%%
