All,

I did end up buying a Raspberry Pi and I am considering using it for a dashboard build (or maybe just cross-compiling for Raspberry Pi on my desktop as a dashboard build).  Either way, the patch from ITK that Mathieu has shared does seem to help and looks okay to me.  If there are no objections I will contribute this patch back to the upstream VXL source.

This patch (taken from ITK) make most issues go away:

http://patch-tracker.debian.org/patch/series/view/vxl/1.14.0-18/sse2.patch

But it was never included in VXL. Maybe there is a good reason for not
including it. As a side note, some x86 machine do not support SSE2
anyway. So VXL is by designed only support on x86 + SSE2.

Thanks,
