Re: [Vxl-users] VNL SSE Problems

[Ian S. <ian...@st...>]

Thanks for the bug report.
I won't be able to look at it on Vista64 for a week or two.
In the mean time I suggest leaving it disabled.

I started noticing that though everything ran without complaint, vnl_matrices and vnl_vectors no longer multiplied together correctly.  Even a simple test case:
