It occurs with cubic_spline & b_spline, and seems fine with
linear_spline. (at least on the provided scene)

So it might be tied to the solver.
On first camera setting, the issue seems to manifest when the ray is in
the same plane as the segment (or they are highly coplanar... yet, two
intersecting lines are always coplanar, that's like stating that 2
points are aligned).

Replacing the difference with an union does not show the issue.

It might be in CSG difference ?
