please help me, I have this code and it throws me that exception.
* Error in `/home/sony/Desktop/recognizingObjects/detectingShapes/chamfer': corrupted double-linked list: 0x0000000002620ee0 * Aborted (core dumped)
I guess it is when i call the function "chamerMatching( img, tpl, results, costs );"
