Martin Sebor updated STDCXX-292:
--------------------------------

              Severity: Compiler Error
     Affects Version/s: 4.1.4
                        4.2.0
                        4.2.1
         Fix Version/s: 4.3
    Remaining Estimate: 4h
     Original Estimate: 4h

Let's see if we can come up with an elegant solution for 4.3.
