Ok, got it. Thank you Sebastien and Efi.

The intersection computation must be used with an exact-predicate-exact-construction kernel. There is no other way.

We are working on fixing the code so that the predicate do_intersect() can be used with an exact-predicate-inexact-construction kernel, but there is no time frame yet.

I doubt there is a difference between the versions and, even if there is it's irrelevant.

Just one more thing too add:
I tested both CGAL 3.8 and CGAL 4.0, and found that this problem is much
more severe in 4.0 than in 3.8.

What do you mean?

Sebastien.

I sincerely hope that this problem could be solved soon since it brings me
lots of troubles (for example, using
Exact_predicates_exact_constructions_kernel will make the computation quite
slow and cause a lot of changes to existing code).
Thanks!
