At least with g++-4.1 on Linux-i686 32bit, I  cannot reproduce the problem
(of adding the six points below), so it  seems to be specific to the
platform you use ... can you post more details about it?

Note that for delaunay triangulation, exact predicates are sufficient - 
exact number type/exact constructions are not required.

Best Regards,
Andreas Meyer

problem is numerical accuracy related. As it has nothing to do with the
number of points you are inserting into the triangulation. In fact if
