Hi all, I have a problem while using cv::format. The error message is as following. My .net environment is win7, 64bit, opencv2.4.2

Windows has triggered a breakpoint in trialtemp.exe.

This may be due to a corruption of the heap, which indicates a bug in trialtemp.exe or any of the DLLs it has loaded.

HEAP[trialtemp.exe]: Invalid address specified to RtlValidateHeap( 0000000000380000, 0000000000398230 ) Windows has triggered a breakpoint in trialtemp.exe.

This may be due to a corruption of the heap, which indicates a bug in trialtemp.exe or any of the DLLs it has loaded.

The source code is as following.

#include <iostream>
#include <cv.h>
#include <cxcore.h>

int main(int argc, char *argv[])
{
  cv::Mat m(4, 2, CV_8UC3);
  cv::randu(m, cv::Scalar::all(0), cv::Scalar::all(255));

  std::cout << "m (default) = " << m << ";" << std::endl << std::endl;
  std::cout << "m (python) = " << cv::format(m,"python") << ";" << std::endl << std::endl;
  std::cout << "m (numpy) = " << cv::format(m,"numpy") << ";" << std::endl << std::endl;
  std::cout << "m (csv) = " << cv::format(m,"csv") << ";" << std::endl << std::endl; 
  std::cout << "m (c) = " << cv::format(m,"C") << ";" << std::endl << std::endl;
}

Looking forward to hear from you. Thanks in advance.

I think you can try to rebuild your OpenCV.

Before rebuilding OpenCV, I used your codes and I got the similar problem like this.

But after rebuilding OpenCV, all things will work well. The codes can work well.

You mean after you rebuilding OpenCV, the codes still cannot work? @ccng

Yes, the code is still not working. So, now I have to use excel convert it manually.
