Hi,

The documentation of the 2D Delaunay triangulation states that the class deals
with duplicate points properly (see
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Triangulation_2_ref/Class_Delaunay_triangulation_2.html#Index_anchor_1651).

The documentation of the *constrained* 2D delaunay triangulation doesn't claim
anything about this (see
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Triangulation_2_ref/Class_Constrained_Delaunay_triangulation_2.html#Index_anchor_1646).

Does it mean the client has to make sur never to insert point twice?

The reason I am asking is because I have a case where the constrained
triangulation deals fine with multiple insertions of the same point and cases
where it crashes. Is it that I am lucky sometimes or that I should fill a bug
report ?
What is the Kernel are you using? Do you have a minimal example showing the pb?

Sebastien.


Thanks for your time.
