Hi,

* Without using OpenCV → no heap leak
* With a simple OpenCV `cv::Mat` → heap leak appears
* Even with larger code, the reported leak size remains the same

This is usually a signature of leak in the library (in this case OpenCV) itself.
It might be that you are not freeing what you've allocated before, or some probably a bug deep in the library itself.
If it is an OpenCV upstream issue which we can't fix, we use the functions to silence to leaks detector of U++. You can find them here.

Best regards,
Oblivion
