Hi Paulo,
Will you run these again with the latest SVN version of numpy. I
couldn't figure out why a copy was being made on transpose (because it
shouldn't have been). Then, I dug deep into the PyArray_FromAny code
and found bad logic in when a copy was needed that was causing an
inappropriate copy.
I fixed that and now wonder how things will change. Because presumably,
the dotblas function should handle the situation now...
