Hi, all

I use Delaunay triangulation in 3D.
The manipulations I want to do is,
first calculating new positions of vertices in Delaunay triangulation,
then move them to the new positions.
When I do it with 
delaunay_triangulation.move_points( vertex handle of vertex, new position );
and I received an message:

Expr: v == V[3]
File: C:/NAGAI/CGAL/CGAL-3.2.1/include/CGAL/Triangulation_ds_cell_base_3.h
Line: 98

I looked above file, but can't understand the meaning of this error
and why this Expr. occurs only for V[3].
Any suggestion will help for me.


Regards,
