           Summary: Dynamic cast is incorrect in some cases
           Product: D
           Version: 1.028
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: dvdfrdmn at users.sf.net


When a class implements an interface that has re-implemented an ancestor
interface, it is possible for a dynamic cast to produce the wrong result.

I have this tagged as "wrong-code", but I believe the problem is due to both
InterfaceDeclaration RTTI and the implementation of
phobos/internal/cast.d:_d_isbaseof2.
