Intersection searcher by Bentley-Ottmann algorithm failure

This is the question I am having lately. I finished this, not working as expected. Actually, it works worst than the easy trivial implementation and sometimes, like now, it does not even work. Should I try again? Would be worth? Choices... For this particular setup, there are 100 lines, 769 intersections found from 1229 total, and 969 events occurred (startpoint | endpoints | intersections).
