I changed code, but it still has problems...

-------------------------------
Conic_arc_2 arclist[] = {arc1, arc2};
std::list<CGAL::Object> ptlist;
Conic_traits_2 traits;
Conic_arc_2 arc1(0,0,0,0,0,0,CGAL::COUNTERCLOCKWISE, Query_Point_2(4,1),
Query_Point_2(6,1));
Conic_arc_2 arc2(0,0,0,0,0,0,CGAL::COUNTERCLOCKWISE, Query_Point_2(5,2),
Query_Point_2(5,0));
CGAL::compute_intersection_points(curlist, curlist+2,
std::back_inserter(ptlist), false, traits);

--------------------------------
The compile error is that:
