Hello,

I'm testing the following code and get a runtime error.

typedef CGAL::Exact_predicates_exact_constructions_kernel Kernel;
typedef CGAL::Nef_polyhedron_3<Kernel>  Nef_polyhedron_3;
typedef CGAL::Plane_3<Kernel>   Plane_3;

        Nef_polyhedron_3 N;
        std::ifstream is;
        is.open("DB1P.nef");
        is >> N;

        Plane_3 pl1(-0, -0.984808, 0.173648, -0);
        N1 = N.intersection(pl1, 
Nef_polyhedron_3::Combine_with_halfspace::CLOSED_HALFSPACE);
        N2 = N.intersection(pl1, 
Nef_polyhedron_3::Combine_with_halfspace::PLANE_ONLY);

The error message given in the console window:

CGAL error: assertion violation!
Expr: itl != it->second.end()
File: e:\lib\cgal-3.3.1\include\cgal\nef_3\snc_external_structure.h
Line: 567
Explanation: <_no explanation here_>

I'm using VS2008SP1 under WinXP/SP1. The test model is attached.

Thanks for any help.

B/Rgds
Max
