Dear Eric,

Please refer to the implementation of the facet checker:

 template <class InputIterator>
    bool test_facet( InputIterator first, InputIterator beyond) {
        // tests if the facet described by the vertex indices in the 
        // range [first,beyond) can be inserted without creating a 
        // a non-manifold (and therefore invalid) situation.
        // First, create a copy of the indices and close it cyclically
        std::vector< std::size_t> indices( first, beyond);
        if ( indices.size() < 3)
            return false;
        indices.push_back( indices[0]);//I think this is the reason.
        return test_facet_indices( indices);
    }
