Hello Amir,

One way to see if this is a robustness issue or a bug in CGAL is to try 
with:

Exact_predicate_exact_constructions_kernel

If you get incorrect results using that then almost certainly there is a bug 
in CGAL.

But conversely, if results are correct using that kernel, then you just have 
a robustness issue which you need to solve by following the advice given.
