I have a bit of a headache trying to understand why simply adding a member variable to OpenCV’s Point_ class makes my program crash. This is one of the classes which comes with OpenCV to store 2D points. If you edit opencv2/core/core.hpp and add a member variable to the class Point_, then the program crashes. See my member variable comment as a comment:

template<typename _Tp> class CV_EXPORTS Point_
{
public:
typedef _Tp value_type;

// various constructors
Point_();
Point_(_Tp _x, _Tp _y);
Point_(const Point_& pt);
Point_(const CvPoint& pt);
Point_(const CvPoint2D32f& pt);
Point_(const Size_<_Tp>& sz);
Point_(const Vec<_Tp, 2>& v);

Point_& operator = (const Point_& pt);
//! conversion to another data type
template<typename _Tp2> operator Point_<_Tp2>() const;

//! conversion to the old-style C structures
operator CvPoint() const;
operator CvPoint2D32f() const;
operator Vec<_Tp, 2>() const;

//! dot product
_Tp dot(const Point_& pt) const;
//! dot product computed in double-precision arithmetics
double ddot(const Point_& pt) const;
//! checks whether the point is inside the specified rectangle
bool inside(const Rect_<_Tp>& r) const;

_Tp x, y; //< the point coordinates
//OCR Additions
bool iAddedThisButItCrashesRemovingMeMakesItWork;
};

Its not just adding a bool. It could be anything like an ‘int i’ as a member variable.

BoundingBox(vector<vector<cv::Point> > &contourPoints, vector<Vec4i> &hierarchy, Mat &imgSrc)
{
    currentContour=0;
    nextContour=0;
    maxContour=0;
    //Is is related to the shallow copy???
    this->contourPoints= contourPoints;  //<----- starts crashing here
    this->hierarchy=hierarchy;
    this->imgSrc = imgSrc;
}

So the runtime exception I get is:

“Debug Assertion Failed!”
“Expression: vector iterator not dereferencable”

I am WTF on this. If anyone has any ideas, please let me know.
