Description

The edition of opencv: 2.4.3
cpu：AMD Phenom(tm) II X6 1055T Processor 2.81 GHz
The platform:win7 64bits
The compiler version:Visual studio 2008

The problem:
     when run the facedetect.exe in C samples,it will crash,and i debug it,it will appear "Illegal Instruction",but the problem disappears when changing to haarcascade_frontalface_alt2.xml.
     It seems this error only happens on AMD CPUs ,the intel cpu is ok.

I hint this problem in Intel CPU using OpenCV 2.4.3 (Both Debug & Release Version)
System: Windows XP SP3 32-bit
CPU: Intel E5200 support SSE

When track into code , I found haveSSE2 is false(in haar.cpp)
bool haveSSE2 = cv::checkHardwareSupport(CV_CPU_SSE2);

Finally, when i run facedetect i get
OpenCVDebug.exe 中的 0x00887013 (opencv_objdetect243.dll) 处未处理的异常: 0xC000001D: Illegal Instruction

Best Regards
