Dear all,

I’m a checking the intersection between Triangle_3 and Plane_3 objects. If
both are constructed from the same triple of points, the result is false for
most triples, but sometimes true. I’m using the exact predicates / inexact
constructions kernel. Is this the expected / desired behavior? I had hope
because of the exact predicates that the result for such intersection tests
is at least consistent (and actually consistently true).

Thanks!
-Marc
