<pre>Consider:
template<typename T> T f();
template<> auto f() { return 0; }
template<> decltype(auto) f() { return 0; }
The second and third lines here are (presumably) ill-formed, because they
deduce a template argument of 'auto' or 'decltype(auto)'. (This is probably a
duplicate of PR20032, which seems to fail for the same reason.)</pre>
