Before the fix, small arc of circle returned as intersection result. It was connected with the fact that the circle always was limited in 0 and 2*PI points. Currently the bounds of the circle (retrieved as an intersection curve) are computed from the real domain of the arguments (there is not a snap to the fixed 0 and 2*PI points).
