           Summary: gcc finds passing reference of template argument as
                    template argument invalid
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: stefaandr at hotmail dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

this code doesn't compile anymore on 3.4, it does on 3.3.1 and before (but I
have no idea if this is a valid or invalid decision or 3.4)
