             Bug #: 52126
           Summary: compilation error
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: tmmikolajczyk@gmail.com


I encountered a compilation error when compiling the following code:

template<typename T>
class A
{
public:
    void foo() {};

    class B : private A<T>
    {
    public:
        typedef A<T> inherited;
        using inherited::foo;
    };
};

The code seems to be valid. Compilation output (the gcc_47_error.cpp file is
attached):
$ g++ --version
g++ (GCC) 4.7.0 20120205 (experimental)
Copyright (C) 2012 Free Software Foundation, Inc.

$ g++ gcc_47_error.cpp
gcc_47_error.cpp:12:26: error: no members matching ‘A<T>::B::inherited::foo’ in
‘A<T>::B::inherited’

It compiles fine with gcc 4.6.2 and clang.
I'm using gcc built manually based on revision 183914.
