Hello all,

CGAL::Parallel_tag doesn't seem to work with CGAL::Triangulation_vertex_base_with_info_3.

Here's the snippet where it's declared:

typedef CGAL::Exact_predicates_inexact_constructions_kernel K;

// Used so that each timeslice is assigned an integer

// typedef CGAL::Triangulation_3<K>  Triangulation;

// typedef CGAL::Triangulation_vertex_base_with_info_3<unsigned, K> Vb;

// typedef CGAL::Triangulation_cell_base_with_info_3<unsigned, K> Cb;

// typedef CGAL::Triangulation_data_structure_3<Vb, Cb> Tds;

// Parallel insertion capable with integer timeslices

typedef CGAL::Triangulation_data_structure_3<

  CGAL::Triangulation_vertex_base_with_info_3<unsigned, K>,

  CGAL::Triangulation_cell_base_with_info_3<unsigned, K>,

  CGAL::Parallel_tag>                           Tds;

typedef CGAL::Delaunay_triangulation_3<K, Tds>  Delaunay;

And here's a snippet of the results:

And the full error log may be found here:

If the CGAL::Parallel_tag is removed, the errors go away.

Thanks for any pointers!
