/*
  Originally reported by chrysn 20100516:

  terminate called after throwing an instance of 'CGAL::Assertion_exception'
   what():  CGAL ERROR: assertion violation!
   Expr: N.is_valid(0,0)
   File: /usr/include/CGAL/convex_decomposition_3.h
   Line: 113

   This appears to have been a CGAL issue and it appears to work correctly in OpenSCAD-2011.12 with CGAL-3.9
