Hi, all,

I am newbie for CGAL and trying to run a simple program as attached:


#include <CGAL/Gmpz.h>
#include <CGAL/Homogeneous.h>
#include <CGAL/Polyhedron_3.h>

typedef CGAL::Homogeneous<CGAL::Gmpz>             Kernel;
typedef Kernel::Point_3                    Point_3;
typedef CGAL::Polyhedron_3<Kernel>         Polyhedron;

int main() {
    Point_3 p( 1.0, 0.0, 0.0);
    Point_3 q( 0.0, 1.0, 0.0);
    Point_3 r( 0.0, 0.0, 1.0);
    Point_3 s( 0.0, 0.0, 0.0);

    Polyhedron P;
    P.make_tetrahedron( p, q, r, s);

    Nef_polyhedron N2(P); // This is where the problem occurs.
    
    return 0;
}

The program halts at "Nef_polyhedron N2(P)". When I run debug, I see it is really in "polyhedron_3_to_nef_3h", at the statement "SM.check_integrity_and_topological_planarity();". It reports there is Unhandled exception from "dbgheadp.c".  I am using Visual Studio 2003 with SP1. 

Can anyone help me figure this out? Thanks.

Joe.
