Hello,

your help actually cleared the fog in my head for a second and i changed the
code like that:

virtual void get_next_diagram(){
                
typedef std::vector<Point_2>          Point_vector;
        
Point_vector pv;
Vertex_iterator vit;
Point_2 p;      
                
for (vit = this->vertices_begin(); vit != this->vertices_end(); ++vit) {
p = Point_2((*vit).point().x(), (*vit).point().y());
pv.push_back(p);
}
this->clear();

for (unsigned int i = 0; i < pv.size(); i++) {

this->insert(pv[i]);
}       
}


It works perfectly. The clear-Function seems have invalidated the vertices
indeed. So i used a point vector instead, saving the points instead of the
vertex references. Like both of you suggested. Thank you very much. I guess i
should have asked the mailing list much earlier.

Good day,

Artyom
