Hello all,

I would like to know if CGAL deallocate and allocate the internal structures (as vertices for example) as we use some functions in Arrangement_2.

I'm asking this because I want to iterate over Arrangement_2 vertices in a specific order so I've created a vector of Vertex pointer and push back to it as I was creating the Arrangement vertices. After that I've tried to iterate over this vector and I'm getting wrong information (and sometimes segmentation fault).

So I was wondering if CGAL deallocate this vertices created in the beginning and allocate it in somewhere else.

Thanks for the help.

PS: I already know the possibility of extending the Vertex class and add an index to it but I need to iterate over this vertices in the most efficient way (O(n)).
