Comment (by robe):

 > I've to say this all sounds to me like a bug in PostgreSQL, not PostGIS.

 Yah sounds like it.  We don't even have an C code behind toTopogeom, it's
 all plpgsql so can't see how we could have screwed that up.

 I'll see if I can create an example that doesn't involve postgis to
 trigger the bug and bounce it back to the PostgreSQL court if I can.
