           Summary: -frepo fails to instantiate typeinfo
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: bgreen@nas.nasa.gov
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: i686-pc-linux-gnu
  GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu

The code presented does not link successfully when using the -frepo option.
The compiler fails to instantiate a typeinfo object in order to perform a
dynamic cast operation.  Failure of the code to link successfully inhibits
library design.
The code builds successfully when not using '-frepo'.
