Hi,

I'm using a CGAL::Arrangment and am trying to connect edges to the intersection of Beziers.

In the application, I'm getting a precondition violation, complaining that the intersection is not rational.

I tried to construct a synthetic example to reproduce the problem, which I've posted on stackoverflow, and it gets a segfault.

https://stackoverflow.com/questions/70107781/cgal-how-can-i-construct-an-edge-between-a-vertex-and-the-intersections-of-two-b

But, assuming the segfault is just a bug, my question is really about the intended API for Beziers. Is it possible to connect an edge to a vertex which is the intersection of two Bezier curves? If so, what's the mechanism I'm supposed to use to avoid the precondition violation?

Thanks in advance for your help.

Kevin
