Looks good.
Comment 3 Raymond Toy 2012-02-06 14:48:13 PST
Actually, this also affects Linux, if the arrays are not aligned for the SSE2 code to be used.

As a side effect, this fixes the test failure on Windows for the convolution-mono-mono test (but 75933).  (Unfortunate that the convolution test was done after bug 74842 was landed.)
