The constructor of CGAL::Polyhedron_incremental_builder has a second 
parameter 
that is a Boolean:
http://doc.cgal.org/latest/Polyhedron/classCGAL_1_1Polyhedron__incremental__builder__3.html#acb8216ef40323e777f57cd4656d98c83

When it is set to 'true', then that class template does extra checks, and 
display diagnostics.

Ilya uses 'true' for the second parameter:
>       typename CGAL::Polyhedron_incremental_builder_3<HDS> B( hds, true);

>       B.begin_surface(_primal.size_of_facets(),
>                       _primal.size_of_vertices(),
>                       _primal.size_of_vertices());

That explains the reported behavior.
