Comment (by pv):

 Ok, apparently the point was that the result is nonzero for the first
 case.

 I note the result array is initialized with zero bytes in _dotblas.c
 before calling BLAS, but it appears it might be possible that it's not
 explicitly initialized in PyArray_MatrixProduct (the inner loops probably
 won't run for dimensions equal 0).
