             Bug #: 52965
           Summary: c++11 - subclass is private, but g++ ignores access
                    modifier when using auto
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jwcacces@yahoo.com


/*
   Is this a bug, that g++ ignores the private access modifier when using "auto
type deduction"?
   Compile with g++ -std=c++0x private_access.cpp
             vs g++ -std=c++0x private_access.cpp -DUSE_AUTO

   This seems similar to bug 52816

#else
