The following sequence of operations produces an object with missing faces:

BRepPrimAPI_MakeBox box1(gp_Pnt(-1,0,0),gp_Pnt(0,3,1));
BRepPrimAPI_MakeBox box2(gp_Pnt(0,0,-1),gp_Pnt(1,2,0));
BRepPrimAPI_MakeBox box3(gp_Pnt(-1,0,-1),gp_Pnt(0,1,0));

TopoDS_Shape shape = box1;
shape = BRepAlgoAPI_Fuse(shape,box2);
shape = BRepAlgoAPI_Fuse(shape,box3);

// Final shape has missing faces
