Dear all,


I am trying to modify the function lloyd_optimize_mesh_2 in order to 
have a parallel computation of all movements. As a reminder, each vertex 
of the triangulation should move to the geometrical center of its cell 
(defined by the voronoi diagram).

When I simulate the threaded behavior (using a serie of different 
function calls), I have to problem and it seems to work. However, if I 
use actual threads, I get an error that occurs at 
Constrained_voronoi_diagram_2.h:360 (this line is 
polygon.push_back(m_cdt.circumcenter(face));)

This error is malloc(): unaligned tcache chunk detected


Thus, my question is for cgal experts: do you think this method could be 
parallel ? is there any static variable that could not be used by 
multiple threads ?

Thank you very much for your time

Yann
