Here is a minimal example:

dist.ist.tugraz.at/delaunaytest.tar.gz

The source code is basically:


#include "CGAL/Exact_predicates_exact_constructions_kernel.h"
#include <CGAL/Delaunay_triangulation_3.h>
#include <CGAL/Triangulation_hierarchy_3.h>
#include <CGAL/Triangulation_vertex_base_with_info_3.h>

typedef CGAL::Exact_predicates_exact_constructions_kernel K;
typedef CGAL::Triangulation_vertex_base_with_info_3<int, K> Vb;
typedef CGAL::Triangulation_hierarchy_vertex_base_3<Vb>  Vbh;
typedef CGAL::Triangulation_data_structure_3<Vbh>        Tds;
typedef CGAL::Delaunay_triangulation_3<K,Tds>            Dt;
typedef CGAL::Triangulation_hierarchy_3<Dt>              Delaunay;

typedef Delaunay::Point Point;
typedef Delaunay::Finite_cells_iterator Finite_cells_iterator;

int main()
{
  Delaunay T;
  T.insert(Point(0,0,0));
  T.insert(Point(1,0,0));
  T.insert(Point(0,1,0));
  T.insert(Point(0,0,1));

  for(Finite_cells_iterator c_it=T.finite_cells_begin();
  c_it!=T.finite_cells_end();++c_it)
  {
        Point p=T.dual(c_it);
  }
  return 0;
}


It compiles with CGAL 3.2.1 but not with CGAL 3.3.0. The error
message is:
