Max, Can you provide an example that's causing you problems? Also, what's the output of cmake, specifically for when volk tests the different SIMD types available? What's your processor and the output of 'cat /proc/cpuinfo'? The reason this doesn't cause a problem for you in 3.3 is because that's pre-Volk. This looks like you're running SSE operations on a system that doesn't support it.
