This test crashes with no warning flags; the crash happens when trying to print

the diagnostic context.



struct vector

{

    typedef int value_type;

};



template< class U, class... T >

struct X

{

    void push_back( typename T::value_type ... vals )

    {

      U::asoeuth;

    }

};



int main()

{   

  X< int, vector > x;

  x.push_back( 0 );

}
