The problem!

I tried compiling following piece of code with “mex”.

Matlab version: R2011a

C++ Compiler: Visual Studio 2010

//test.cpp
#include "mex.h"
#include <vector>
#include <opencvcv.h>
void mexFunction(int nlhs, mxArray *plhs[],int nrhs, mxArray *prhs[])
{
    int size[]={100,100,3};
    const std::vector<cv::Mat> chans(size[2],cv::Mat(size[0],size[1],CV_64F));
    cv::Mat opencv;
    cv::merge(chans,opencv);
    return ;
}

This compiles fine. But crashes Matlab, if you run “test” in Matlab. In debug mode (“mex” with -g), leads to an assertions failure !
