In fact, this version has a problem too, but you are just lucky. The 
function is provided a copy of the Delaunay triangulation, which will be 
discarded after the call. In particular, the vertex_handles extracted 
from this copy will then be meaningless.

In order to avoid this costly (and harmful in this case) copy, you 
should pass a reference to the Delaunay triangulation instead. In this 
case, it should even be a const reference, since you are just reading 
the triangulation:

Planar_Segment create_segments_TDS(const Delaunay& dt)
