--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
With 4.7 I get the maybe informative

t.ii:5:55: error: 'my_make_pair' function uses 'auto' type specifier without
trailing return type
t.ii: In instantiation of 'mypair<T*, int> S<T>::get_pair() [with T = char]':
t.ii:23:19:   required from here
t.ii:12:36: error: 'my_make_pair' was not declared in this scope
t.ii:23: confused by earlier errors, bailing out

thus we miss the error in 4.8.x and 4.9 (but ICE the same later).

Marking as accepts-invalid regression.  After that it would be an
error-recovery
ice-on-invalid.
