--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, fully reduced testcase:
```
template <typename... Ts> struct tuple {};
template <int... Ts> struct seq {};
template <typename TT, typename... Ts, int... i>
inline auto sfinae_friendly_apply_impl(TT invocable, tuple<Ts...> t, 
seq<i...>) noexcept
    -> decltype(invocable(get<i>(t)...)) {}
void run_all() {
  sfinae_friendly_apply_impl([](){}, tuple<>{}, seq<>{});
}
template<int i, typename T> int get(T);

```

Note moving the definition of get before the definition of
sfinae_friendly_apply_impl allows GCC to work.

    c++: mangling template-id of unknown template [PR110524]

    This fixes a crash when mangling an ADL-enabled call to a template-id
    naming an unknown template (as per P0846R0).

            PR c++/110524

    gcc/cp/ChangeLog:

            * mangle.cc (write_expression): Handle TEMPLATE_ID_EXPR
            whose template is already an IDENTIFIER_NODE.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/fn-template26.C: New test.
