and error happens ate point, when use copy constructor:

coords(const coords& coord){     this->order = coord.order;     this->x = coord.x;     this->y = coord.y;     this->node = new unsigned int[order + 1];     (int ii = 0; ii < (order + 1); ii++) this->node[ii] = coord.node[ii];     this->reg = coord.reg; }

how can solve it, please? i've looked @ many places , found use valgrind, guess not necessary, since using std class.
