Hi guys,

I am testing the example code and I got a precondition violation error.
<http://cgal-discuss.949826.n4.nabble.com/file/n4661966/1.png>

The link to the example code is closed.
http://doc.cgal.org/latest/Voronoi_diagram_2/Voronoi_diagram_2_2vd_2_point_location_sdg_linf_8cpp-example.html

The following is a section of my code (VDA is a Voronoi_diagram_2 instance).
I got the error when I call the ccb function [(*f)->ccb()]. Basically I want
to find the face the query point locates at and visit all the vertices that
face consists of.

I have no idea about what is happening here. SOS.
