In the lambda expression's compound statement, id-expressions referring to non-static members should be transformed into class member access expressions by prefixing `(*this).'. However, GCC fails the transformation when id-expressions involved are qualified-ids and refer to dependent base members.

A test case is as follows;

////////////////////////////////////////////////////////////////////
struct B
{
  int get() const { return 42; }
};

template<typename X>
struct D
  : public X
{
  int get() const { return [this]() -> int { return X::get(); }(); }
};

int main()
{
  D<B> d;
  d.get();
}

////////////////////////////////////////////////////////////////////

For the above mentioned well-formed code, 4.7.0 20120218 (experimental) with -std=c++11 complains as follows;

main.cpp: In instantiation of 'D<X>::get() const [with X = B]::<lambda()>':
main.cpp:10:29:   required from 'struct D<X>::get() const [with X = B]::<lambda()>'
main.cpp:10:65:   required from 'int D<X>::get() const [with X = B]'
main.cpp:16:9:   required from here
main.cpp:10:60: error: cannot call member function 'int B::get() const' without object

`X::get' in the lambda expression should be implicitly transformed into `(*this).X::get', and the test case should compile successfully.
