Hello all,

The method CGAL::Arr_polyline_traits_2<SegmentTraits>::Curve_2::push_back
has a precondition: the Curve_2 object has to be non empty. If push_back is
called
while the Curve_2 is empty, it causes a segmentation fault.

I use this configuration:

typedef CGAL::Exact_predicates_exact_constructions_kernel  Kernel;
typedef CGAL::Arr_segment_traits_2<Kernel>                    
Segment_traits;
typedef CGAL::Arr_polyline_traits_2<Segment_traits>          Traits;
typedef Traits::Curve_2                                                   
Polyline_2;

Does the problem occur only in my case ? Should it be a CGAL::precondition
violation
instead of a segfault?

Anyway, thanks for the work done for the whole Arrangement_2 package. It is
really
helping me a lot.

Best regards,
