Hi Laurent

I've added the assertion but the problem still occurs. Here is the code. It produces the two different precondition errors on both CGAL 3.5.1 and 3.6. The call to refine_Delaunay_mesh_2 is on line 62 of trigen.cpp.

thanks!
  Simon

Strange. Can you call "assert(tr.is_valid());" before you call
refine_Delaunay_mesh_2?

If that assertion is correct, I would appreciate that you post your code, so
that I can reproduce the error on my machine.
