Dear Dr. Loriot,

Thank you very much for your kindly reply. I modified that file as follows:

void
generic_print_polyhedron( std::ostream&     out, 
                          const Polyhedron& P,
                          Writer&           writer) {
    // writes P to `out' in the format provided by `writer'.
    typedef typename Polyhedron::Vertex_const_iterator                  VCI;
    typedef typename Polyhedron::Facet_const_iterator                   FCI;
    typedef typename Polyhedron::Halfedge_around_facet_const_circulator
HFCC;
    // Print header.
    writer.write_header( out,
                         P.size_of_vertices(),
                         P.size_of_halfedges(),
                         P.size_of_facets());
    for( VCI vi = P.vertices_begin(); vi != P.vertices_end(); ++vi) {
//        writer.write_vertex( ::CGAL::to_double( vi->point().x()),
//                             ::CGAL::to_double( vi->point().y()),
//                             ::CGAL::to_double( vi->point().z()));
        out << '\n' << vi->point().x()
            << ' '  << vi->point().y()
            << ' '  << vi->point().z();
    }
...

and the output OFF files are attached. However, when do Boolean operations
by the program, the program crashed and the call stack is as follows:

        booleantest.exe!main()  Line 61 C++


Could you please help me to take a look at it?

Thanks,
