Hi Andre,

I didn't get a close look on your problem, but i see you are using a 
non-filtered kernel (Simple_cartesian<double>). If you switch to a 
filtered kernel (e.g. 
CGAL::Exact_predicates_inexact_constructions_kernel), you should avoid 
such failures (your attached file runs ok with epic kernel).

Best,
