If the matter is data alignment, perhaps this is because of memory 
allocators or the BLAS library functioning differently on different 
platforms.

To get a definite answer if the issue is data alignment, one can perhaps 
check if the different results are correlated with

	input_array.__array_interface__['data'][0] % 16

(assuming no copies are made inside dot()).
