           Summary: ICE on type_unification_real
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: gcc-bugzilla at x-infinity dot com
                CC: gcc-bugs at gcc dot gnu dot org

The following output illustrates the ICE.
I'm not sure if this code should compile or is even syntactically correct, but 
ICE is still there.
