I get the following error when subtracting two Nef polyhedra

ERROR: CGAL ERROR: assertion violation!

Expr: itl != it->second.end()

File: /usr/local/include/CGAL/Nef_3/SNC_external_structure.h

Line: 1102

I have attatched the polyhedra in "off" format.  They convert fine to Nef_polyhedron_3.  I have also tried the operation with the "Operations on Polyhedra" demo.  Performing the difference operation (stock - design) also crashes it.

Thanks in advance.
