            Bug ID: 60241
           Summary: internal compiler error: in finish_member_declaration,
                    at cp/semantics.c:2617
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal

I've got internal compiler error on the following code:

template <typename T>
struct x
{
    template <typename U>
    struct y
    {
        typedef T result2;
    };

    typedef y<int> zy;
};

template<>
template<class T>
struct x<int>::y
{
    typedef double result2;
};

int main()
{
    x<int>::zy::result2 xxx;
    x<int>::y<int>::result2 xxx2;
}

6.cpp: In instantiation of 'struct x<int>::y<int>':
6.cpp:23:19:   required from here
6.cpp:16:1: internal compiler error: in finish_member_declaration, at
cp/semantics.c:2617

Confirmed.  Probably invalid as 4.3 errors:

t.C:15: error: specialization ‘x<int>::y<U>’ after instantiation
‘x<int>::y<int>’

Likely caused by r149188 (r149186 works, r149196 fails).
