std::vector of cv::Mat causing memory corruption

edit

I am using opencv_contrib's ximgproc moule's structural edge detector's code in my visual studio project . But it giving _CrtIsValidHeapPointer(pUserData) error expression . With some debugging I realized that Actually the error is caused when a function getFeatures defined in structured_edge_detector.cpp tries to push cv::Mat in a std::vector as shown below

virtual void getFeatures(const Mat &src, Mat &features, const int gnrmRad, const int gsmthRad,
                         const int shrink, const int outNum, const int gradNum) const
{
    cv::Mat luvImg = rgb2luv(src);

    std::vector <cv::Mat> featureArray;

    cv::Size nSize = src.size() / float(shrink);
    split( imresize(luvImg, nSize), featureArray );

    CV_INIT_VECTOR(scales, float, {1.0f, 0.5f});

    for (size_t i = 0; i < scales.size(); ++i)
    {
        int pSize = std::max( 1, int(shrink*scales[i]) );
    }
    mixChannels(featureArray, features, fromTo);
}

Please tell me what is the reason of such fault in program and any possible solution. My Opencv version is 2.4.10 so I am actually using the ximgproc's structured edge detector's code within my project.

Thanks
