This would be the first ever example of this sort of thing in my

of Split on the Mac and other platforms (Carl and I were involved in 
discovering this phenomenon that was never really explained)  but we 
attributed this to differences at operating system level, probably 
memory management or maybe even hardware. But this case would be 
differencing the issue is unpacking of packed arrays, something that is 
obviously in the Mathematica code. I have always believed that the 
basic Kernel code is written in C++ and then compiled for various 
platforms on which Mathematica runs which would mean that such a thing 
could not happen, but perhaps this is no longer the case (if it ever 
was the case).
