Description

When I configure the 2.4.3 for Visual Studio 2010 x64, all features as default except disabling CUDA, the Haarcascade class does not detect anything anymore.
Additionally the average time drops from around 100ms per turn to 10ms per turn.

I "fixed" this by hard overwriting haveAVX with false in the cvRunHaarClassifierCascadeSum function.

It's anyway interesting that it seems to have CV_HAAR_USE_AVX set although ENABLE_AVX is not checked in the CMAKE config.

If I compile it for 32 bit and let it keep the haveAVX flag true it works fine.

The CPU is a Core i7-3632 QM.
