Hello

I'm trying to use the I/O functions to write and read an arrangement to a file. The problem is that when I try to read the arrangement from the file the program get stucked. I'm using a very simple program to test and I already checked the file generated by write and it is not empty. My .cpp code:

  Arrangement_2 arr1,arr2;
  Point_2 p1 (1 , 3 ) , p2 (3 , 5 ) ;
  XSegment_2 s1 (p1 , p2 ) ;

  Arrangement_2::Halfedge_handle e1 = arr1.insert_in_face_interior( s1 ,arr1.unbounded_face( ) ) ;
  Vertex_handle v1 = e1->source();

  ofstream out_file("arr_ex_io.dat");
  out_file << arr1;
  out_file.close();


  ifstream in_file("arr_ex_io.dat");
  in_file >> arr2;
  in_file.close();

Anyone had the same problem? Thanks in advance
