this line should be replaced by t, itBegin, itEnd

Do you mean this will solve the problem ?

However, the crash I was meeting was not the one you mention in the title message.

Summary of Changes
I am trying to modify the function lloyd_optimize_mesh_2 in order to have a parallel computation of all movements.
When I simulate the threaded behavior (using a serie of different function calls), I have no 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
