My code can run correctly on 32-bit linux machine (Ubuntu 10.10), however,
when I run it on a 64-bit linux machine (CentOS_5.4), it failed. Below is
some detailed information. Can anybody help?  Thank you very much!

-----same code on both machines-----

typedef Kernel::Point_2                                   Point_2;

typedef CGAL::Polygon_with_holes_2                Polygon_with_holes_2;
typedef std::list                   Pwh_list_2;

template 
typename CGAL::Polygon_2<Kernel, Container>::FT
overlap_area(const CGAL::Polygon_2<Kernel, Container> &P,
                         const CGAL::Polygon_2<Kernel, Container> &Q)
{
        CGAL_precondition(P.is_simple());
        CGAL_precondition(Q.is_simple());

        Pwh_list_2 overlap;
        cerr<<"before calling CGAL::intersection: \nP="<<P<<"\nQ="<<Q<<endl;
        CGAL::intersection(P, Q, std::back_inserter(overlap));
        cerr<<"after calling CGAL::intersection"<<endl;
        exit(1);
}
