I am trying to create a STL map of type map<int,CGAL::AABB_tree&lt;Traits>>
(map of AABB tree's) when I try to assign a value to the map, for example
(this code is only for demonstration purposes): 

//CGAL includes begin 
#include <CGAL/Simple_cartesian.h>
#include <CGAL/Polyhedron_incremental_builder_3.h>
#include <CGAL/AABB_tree.h>
#include <CGAL/AABB_traits.h>
#include <CGAL/Polyhedron_3.h>
#include <CGAL/AABB_face_graph_triangle_primitive.h>
//CGAL includes end 
/* 
 * CGAL typedef's for initialization 
 */ 
typedef CGAL::Simple_cartesian<double>                          K; 
typedef K::FT                                                   FT; 
typedef K::Point_3                                              Point_3; 
typedef K::Segment_3                                            Segment; 
typedef CGAL::Polyhedron_3<K>                                   Polyhedron; 
typedef Polyhedron::HalfedgeDS                                  HalfedgeDS; 
typedef Polyhedron::Vertex_const_iterator                      
Vertex_const_iterator; 
typedef Polyhedron::Facet_const_iterator                       
Facet_const_iterator; 
typedef Polyhedron::Halfedge_around_facet_const_circulator     
Halfedge_around_facet_const_circulator; 
typedef CGAL::AABB_face_graph_triangle_primitive<Polyhedron>    Primitive; 
typedef CGAL::AABB_traits<K, Primitive>                         Traits; 
typedef CGAL::AABB_tree<Traits>                                 Tree; 
typedef Tree::Point_and_primitive_id                           
Point_and_primitive_id; 
//end of typedef's 

BuildMesh<HalfedgeDS> mesh(V, F); 
polyhedron.delegate( mesh); 
myMap[someInt] =
Tree(polyhedron.facets_begin(),polyhedron.facets_end(),polyhedron); 
I get the following error: 

error C2248: 'CGAL::AABB_tree< AABBTraits >::operator =' : cannot access
private member declared in class 'CGAL::AABB_tree< AABBTraits>' 

I tried looking in the source code of CGAL and found in CGAL\AABB_tree.h the
following lines: 

private: 
        // Disabled copy constructor & assignment operator 
        typedef AABB_tree<AABBTraits> Self; 
        AABB_tree(const Self& src); 
        Self& operator=(const Self& src); 
this means that the copy and assignment constructors are private, thus it's
not possible to create stl containers of type Tree. 

I tried to use pointers instead I changed my map to map<int,CGAL::AABB_tree
&lt; Traits > *  > and tried: 

BuildMesh<HalfedgeDS> mesh(V, F); 
polyhedron.delegate( mesh); 
myMap[someInt] = new
Tree(polyhedron.facets_begin(),polyhedron.facets_end(),polyhedron); 
but then it crashed my code. 

Is there any way around it so it will be possible to create an STL container
of this type?
