Doubt in Bounding Rectangle Algorithm

i cannot repeat any problem from the issue using c++:


for (int h :{3,4,5,6,7,8,9}) {
    for (int w :{5,6,7,8,9,10}) {
       Mat m(h,w,CV_8U,Scalar(0));
       m(Rect(w-3,h-1,3,1)) = 1;
       //cout << m << endl;
       Rect r = maskBoundingRect(m); // see post above
       Rect r2 = boundingRect(m);
       cout << (r==r2) << " " << r <<  r2 << endl;
    }
}
