Hello,

like I've said before, I'm making an application that takes a set of points and create a convex hull for those points. I had some problems with my code because I was using the Cartesian kernel, not the Exact_predicates_inexact_constructions_kernel, for treat double numbers. But now that I changed the kernel, when I call the convex_hull_3 function, the program makes an access  violation (Unhandled exception at 0x104817fd (msvcp80d.dll) in ConstrainedDelaunay.exe: 0xC0000005: Access violation writing location 0xcccccccc.)

I have no idea what this could be. Does any body have any clue where I'm wrong?

The code is the follow ---------------------------------------
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Convex_hull_traits_3.h>
#include <CGAL/convex_hull_3.h>
#include <iostream>
#include <fstream>
#include <vector>

typedef CGAL::Exact_predicates_inexact_constructions_kernel Kernel;
typedef CGAL::Convex_hull_traits_3<Kernel>                  Traits;
typedef Traits::Polyhedron_3                                Polyhedron;

typedef Kernel::FT                                          Field_number;
typedef Kernel::Point_3                                     Point;

using namespace std;

int main(){
    ifstream file;
    file.open("resources/geometry.txt");
    vector<Point> points;
    Field_number x, y, z;

    while (!file.eof()) {
       file >> x >> y >> z;
       Point point(x, y, z);
       points.push_back(point);
    }

    Polyhedron polyhedron;

    CGAL::convex_hull_3(points.begin(), points.end(), polyhedron);

    return 0;
}
-----------------------------------------------------------------------

Thank you all,
