Hi all,

When I try to use this very trivial code:

#include <CGAL/basic.h>
#include <CGAL/Gmpq.h>
#include <CGAL/Homogeneous.h>
#include <CGAL/Nef_polyhedron_3.h>

typedef CGAL::Gmpz NT;
typedef CGAL::Homogeneous<NT> Kernel3D;
typedef Kernel3D::Point_3                                      Point3D;
typedef CGAL::Iso_cuboid_3<Kernel3D>                           Cuboid3D;
typedef CGAL::Nef_polyhedron_3<Kernel3D>                       Polyhedron3D;

using std::vector;

int main(int argc, char** argv)
{

 Cuboid3D c1(Point3D(0,0,0), Point3D(3,3,3));
 vector<Point3D> vp;
 for(u_int i=0; i<8; ++i)
   vp.push_back(c1[i]);

 Polyhedron3D p(vp.begin(), vp.end(), true);
}

Execution fails with the following error:
"Conversion from vertex cycle to Nef_polyhedron_3 was not successful. 
Error history: Direction of projection is 'z'. -> Different vertices are 
projected to same location! Now, direction of projection is 'x'. -> 
Different vertices are projected to same location! Now, direction of 
projection is 'y'. -> Different vertices are projected to same location! 
Finally, empty Nef_polyhedron_3 was constructed."

Am I doing wrong something, or is there a bug in Nef_polyhedron_3 (II 
v_first, II v_last) ?

Thanks for responses.
