Hello,

I have been trying to write code that, given a vertex and element list,
builds a CGAL::Polyhedron_3. I am using the code from:
http://jamesgregson.blogspot.com/2012/05/example-code-for-building.html. 

I first mesh a sphere, then I attempt to use the above code to generate the
Polyhedron_3. However, I get the following error: 

CGAL::Polyhedron_incremental_builder_3<HDS>::
lookup_halfedge(): input error: facet 11 shares a halfedge from vertex 17 to
vertex 33 with facet 10.
Segmentation fault: 11

What's going on? When I place the sphere in a .OFF file and pass it to the
example program Mesh_an_implicit_mesh.cpp, there is no problem. However, I
would like to pass the vertex and element list directly and thus have to
build the Polyhedron_3 myself.

Thanks!
