Hi!

I want to test if a given Point lies on a segment:

Code:
typedef CGAL::Point_2<Voronoi_K> Voronoi_Point;
typedef Voronoi_K::Ray_2 Voronoi_Ray;
typedef Voronoi_Triangulation::Segment Voronoi_Segment;
typedef std::vector<Voronoi_Point> VDPointContainer;

//---------------------------------------------------------------------
bool hasIntersectionSegmentWithPoints(Voronoi_Segment s, VDPointContainer& 
points) {
  std::cout <<"Has the Voronoi_Segment an intersection with a point?" << 
std::endl ;
  VDPointContainer::iterator it;
  for( it = points.begin(); it != points.end(); it++ ) {
    cout << "Checking point " << *it << endl;
    if (s.has_on(*it)) {
      return true;
    }
  }
  return false;
}

Output:
Has the Voronoi_Segment an intersection with a point?
Checking point 0.5 0.5
CGAL error: assertion violation!
Expr: !(i>s)
File: /home/TZi/CGAL-3.3/include/CGAL/Interval_nt.h
Line: 77
Explanation: Variable used before being initialized (or CGAL bug)
Aborted (core dumped)

Any idea what's wrong?

Best regards,
