Martin Sebor updated STDCXX-680:
--------------------------------

           Description: The function that is called by has_facet<>() and use_facet<>()
uses _RWSTD_DYNAMIC_CAST in an attempt to check that the returned locale facet is of the requested

              Priority: Minor  (was: Major)
     Affects Version/s: 4.1.2
                        4.1.3

         Fix Version/s: 4.3
    Remaining Estimate: 2h
     Original Estimate: 2h

Let's try to make a decision how to deal with this in 4.3.
