Summary0002499: Crash on cloning operations (sketcher)
DescriptionThe application crashes when trying to clone an object onto a specified location (point lock).
I am using hexagon objects to create honeycomb patterns.
Steps To ReproduceFrom the sketch in the attached file, select internal hexagon (select the entire region), then choose the cloning tool and choose as the point to clone onto any of the vertices of the outer construction line hexagon. The application gets killed.

Observation. If I clone the same objetc onto a nearbye point and than constrain the center point of the two objects to a coincidence point the operation succeeds and I can change the constraints without problems.

One more curiosity about the behavior of the cloned object. If I select the interior hexagon and then clone it onto a point located far from the vertex of the outer hexagon such that the cloned object does not intersect the vertex or arest of the outer hexagon and then apply the point constraint to the center point of the cloned hexagon and the vertex of the outer hexagon the construction circle get moved to the right position but the hexagon apparently collpses to a single point.

A "wild ass guess" or a "pitaco" (pee-tah-cko) (Braz-port) for the behavior described.
It might just happen that the solver is being fooled by a trivial solution. A zero length line or an hexagon inscribed in a null diameter circle will satisfy the system of equations. A check might be run to prevent this to happen.
