我的任务
分享莫名奇妙的“读取位置 0xccccccd4 时发生访问冲突”求大神指教
在网上下了一个开源库，结合了opencv，自己单步调试，已经知道了问题的所在代码行，可是实在无解，求大神帮助，现将问题描述如下：
其中SetConfiguration已经做成了lib文件，单步调试之后进入源码：
主要进入上面if语句中的load函数，这个是opencv的CascadeClassifier，即导入xml文件，可是在调试程序的时候就是断了。
在这个load之前，注释了的那句：
是我注释掉了，要不然程序在这句断了，出现的错误提示是rep movsd;N - move all of our dwords
这句就更加不能理解了，不就是简单的赋值吗？怎么还会出现这种错误呢？
自己实在搞不定了，还请求版上的各位大神帮忙，谢谢！
const string frontalface="D:\\study\\opencv\\data\\lbpcascades\\lbpcascade_frontalface.xml";
const string profileface="D:\\study\\opencv\\data\\haarcascades\\haarcascade_profileface.xml";
const string lefteye="D:\\study\\opencv\\data\\haarcascades\\haarcascade_mcs_lefteye.xml";
const string righteye="D:\\study\\opencv\\data\\haarcascades\\haarcascade_mcs_righteye.xml";
const string nose="D:\\study\\opencv\\data\\haarcascades\\haarcascade_mcs_nose.xml";
const string mouth="D:\\study\\opencv\\data\\haarcascades\\haarcascade_mcs_mouth.xml";
cv::CascadeClassifier facedetect;
facedetect.load(frontalface);
fd.SetConfiguration(frontalface, profileface,lefteye,righteye,nose,mouth,VO_AdditiveStrongerClassifier::BOOSTING,CFaceDetectionAlgs::FRONTAL );其中SetConfiguration已经做成了lib文件，单步调试之后进入源码：
void CFaceDetectionAlgs::SetConfiguration( const string& strfrontalface,
const string& strprofileface,
const string& strlefteye,
const string& strrighteye,
const string& strnose,
const string& strmouth,
unsigned int mtd,
unsigned int facetype)
{
switch(this->m_iDetectionMethod)
{
case VO_AdditiveStrongerClassifier::BOOSTING:
default:
{
if(strfrontalface!="")
{
//this->m_sFile2BLoadFrontalFace = strfrontalface;
this->m_cascadeClassifierFrontalFace.load( strfrontalface);
}
}
}主要进入上面if语句中的load函数，这个是opencv的CascadeClassifier，即导入xml文件，可是在调试程序的时候就是断了。

按f11逐步进入调试吧，看看是哪个位置出问题，同时注意提头说那个地址是属于哪个变量的

崩溃的时候在弹出的对话框按相应按钮进入调试，按Alt+7键查看Call Stack里面从上到下列出的对应从里层到外层的函数调用历史。双击某一行可将光标定位到此次调用的源代码或汇编指令处。
判断是否越界访问，可以在数组的最后一个元素之后对应的地址处设置数据读写断点。如果该地址对应其它变量干扰判断，可将数组多声明一个元素，并设置数据读写断点在该多出元素对应的地址上。

刚看错了，这个也是一个私有变量

这是这个类的私有变量：
CascadeClassifier m_cascadeClassifierFrontalFace;
cv::CascadeClassifier facedetect;
facedetect.load(frontalface);

this->m_sFile2BLoadFrontalFace 是什么数据类型？看起来应该是这个地方有问题，那个地址感觉是非法地址
