Summary

0031147: BRepOffsetAPI_MakePipeShell null access

Description

    TopoDS_Wire aSpine = ... ;//"pipeShell-fail.brep"
    TopoDS_Wire aWire = ... ;//"pipeShell-fail.brep"

    BRepOffsetAPI_MakePipeShell aMakePipe(aSpine);
    aMakePipe.Add(aWire, Standard_False, Standard_False);

    aMakePipe.SetTransitionMode(BRepBuilderAPI_RoundCorner);
    aMakePipe.SetDiscreteMode();
    aMakePipe.SetTolerance();
    aMakePipe.Build();

// Null access occurs as below function stacktrace:
