Comment (by mdavis):

 Replying to [comment:6 Paul Ramsey <pramsey@…>]:

 > Curiously, this case blows an exception on PostGIS, but not in the unit
 test.

 The reason the unit test passes is that the triangulation tolerance value
 (100) is larger than the extent of the input geometry.  This causes the
 data to collapse to a point, which produces an empty Voronoi diagram.  If
 a smaller tolerance (say 0.1) is used then the test fails with a Topo
 exception.
