Hello All,  
I am facing problem in rectangle function and filter2D while using OpenCV4.6 in C++ on Linux system. OpenCV 4.3 version is working absolutely fine. I have checked all .hpp files are also in place.  
Please advice why its happening so

segmentation fault is coming and when the control of program reaches at rectangle function it crashes and similarly for filter2D

Point p1(270,415);  
Point p2(470,615);  
if (check==1)  
rectangle(img, p1, p2, Scalar(255,255,255,1));

When it accesses rectangle function from imgproc it crashes
