Did you add the normal map (point_set.add_normal_map()) before calling 
normal estimation? From your first mail, it seems that you did, but I 
just want to check (as a missing normal map could lead to this error).

You're saying that it happens on large data sets after a long time: how 
large is it? Is it possible that it exceeds the memory limits of your 
computer? (How much RAM do you have?)

The class CGAL::Point_set_3 relies on some internal code that is from 
the Surface_mesh package.

Best,
