Dear everyone,

I am trying to use make_mesh_3 in parallel mode. While my code runs without
any problems in sequential mode in parallel mode I am getting the following
error:
   what():  CGAL ERROR: assertion violation!
   Expr: v == V[3]
   File: ./libs/CGAL/CGAL-5.1/include/CGAL/Triangulation_ds_cell_base_3.h
   Line: 93

The relevant code snippets are as follows:
typedef CGAL::Labeled_mesh_domain_3<Kernel> Implicit_domain;
typedef CGAL::Mesh_triangulation_3<Implicit_domain, CGAL::Default,
Concurrency_tag>::type VTr;
typedef CGAL::Mesh_complex_3_in_triangulation_3<VTr> C3t3;
typedef CGAL::Mesh_criteria_3<VTr> Mesh_criteria;

///////

aClassContainingTPMSequations *tpms

///////

auto myImplicitFunction = [dist, tpms](const Point_3 &p) { 
  return dist->signed_distance_function(p, dist->
poissonReconstructionFunction, tpms); 
}; // To pass function on as a static member

Implicit_domain domain =
Implicit_domain::create_implicit_mesh_domain(myImplicitFunction,
boundingBox);

Mesh_criteria criteria(CGAL::parameters::facet_angle = facetAngle,
                               CGAL::parameters::facet_size = facetSize,
                               CGAL::parameters::facet_distance = 
facetDistance);
C3t3 c3t3 = CGAL::make_mesh_3<C3t3>(domain, criteria,
CGAL::parameters::manifold());

///////


I also tried running make_mesh_3 without manifold() in which case it just
keeps on running forever.

Hopefully someone can point me in the right direction.

Kind regards,
Kim
