Summary0033891: With BRepAlgoAPI_Common, creatation an edge with an INTERNAL orientation and linked to a single face
DescriptionWith BRepAlgoAPI_Common, I manage to create an edge with an INTERNAL orientation and linked to a single face, and this edge seems to have no meaning. This is a bad artifact because my resulting shape is not considered as manifold since there is only one connection for this edge, instead of 2.

Tried with v7.9.1
Steps To Reproduce        BRepAlgoAPI_Common lBuilder ;
        lBuilder.SetRunParallel(false) ;
        TopTools_ListOfShape lArgs ;
        TopTools_ListOfShape lTools ;
        lArgs.Append(lShape) ; // File arg.brep
        lBuilder.SetArguments(lArgs) ;
        lTools.Append(lTool) ; // File tool.brep
        lBuilder.SetTools(lTools) ;

        if (pFuzzyValue > 0.0)
        {
            lBuilder.SetFuzzyValue(pFuzzyValue) ;
        }

        lBuilder.Build() ;

        if (lBuilder.IsDone())
        {
            if (!lBuilder.HasErrors())
            {
                lShape = lBuilder.Shape() ; // File res.brep
            }
        }

In res.brep we can see an existing edge with INTERNAL orientation and only 1 linked face. That wasn't exist in the 2 input shapes.
