Summary0000418: Sketcher - When pading I get unclosed shape

This one is easy to reproduce

Place two arcs so that they have center at the same point - use coincidence on their center

Then place two lines so that the shape gets to be closed - use coincidence between lines and arcs

you can see the shape you get when you pad this

Using arcs leads to an error somewhere in the model. Calling the check() method of the resulting solid shows the error message that a few faces are unorientable.
But e.g. with fix(0.0001,0.0001,0.0001) the solid is repaired and shows the missing faces.

I have tested other arcs, and the problem appears only if two arcs have coincidence constraint in centers.

other cases do not post this issue.

Here is an example which also fails with two not-coincident arc centers:
