I get:

CGAL error: precondition violation!
Expression : (squared_radius >= FT(0)) & (o != COLLINEAR)
File       : C:\prj-external-libs\CGAL\include\CGAL/Cartesian/Sphere_3.h
Line       : 59

The problem seems to be in AABB_traversal_traits.h:

  bool do_intersect(const Point& query, const Node& node) const
  {
    return m_traits.compare_distance_object()
      (query, node.bbox(), m_closest_point) == CGAL::SMALLER;
  }

where m_closest_point has NaN coordinates.

My code:
        typedef CGAL::Simple_cartesian<double> Enriched_kernel;
        typedef CGAL::AABB_face_graph_triangle_primitive<Mesh2> Primitive; // 
Mesh2
derives from Polyhedron_3
        typedef CGAL::AABB_traits<Mesh2::Kernel, Primitive> AABB_traits;
        typedef CGAL::AABB_tree<AABB_traits> Tree;

        Tree tree(mesh2->facets_begin(), mesh2->facets_end(), *mesh2);

        double dist = sqrt(tree.squared_distance(vi->point())); // vi is a 
vertex
in another poly
