0031111: Boolean fails for two simple extrusion
The file uploaded "boolean fails.brep" to reproduce the issue

TopoDS_Shape aBlankShape = // the first object in "boolean fails.brep"
TopoDS_Shape aToolShape = // the second object in "boolean fails.brep"

BRepAlgoAPI_Cut aMakeCut(aBlankShape, aToolShape);

Above code will reproduce the Boolean fails issue. It sometimes works after swapping aBlankShape and aToolShape.
No tags attached.
