Hi, I get a crash when I try to 3D-mesh your geometry (gmsh 2.8.5, Windoze 7). So I cannot really see what happens. Before doing the 3D mesh, you could have a look at the 2D mesh to see if it corresponds to what you expect. If 3D meshing fails, gmsh normally creates a file with intersections (intersect.pos if I remember correctly), which you can merge to your geometry to see where the self-intersections are.
