Hmmm, difficult to see :P

Ok, thanks!

Search for the differences:
http://www.cgal.org/Manual/3.5/doc_html/cgal_manual/STL_Extension_ref/Class_Object.html
http://www.cgal.org/Manual/3.6/doc_html/cgal_manual/STL_Extension_ref/Class_Object.html



You should upgrade to CGAL-3.6 (whose documentation you refer to), or not use
is<T>(). If you want to stick to CGAL-3.5.1, instead of:
 obj.is<T>()
you can use:
 CGAL::object_cast<T>(&obj) != NULL
