------- Comment #3 from rguenth at gcc dot gnu dot org  2008-09-21 11:30 -------
In 4.2 the offending code was removed so we no longer ICE (the "wrong -1"
problem remains - casting -1 to size_type_node causes the overflow flag to
be set).

So, fixed for 4.2.0 - the 4.1 branch is no longer maintained.
