--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
So is this a rejects-valid as well? The assert suggests the return value and
the diagnostic without checking is wrong:
> g++-11 t.C -c
t.C: In instantiation of 'int f(S<int>)':
t.C:16:10: required from here
t.C:6:14: error: 'int S<const int>::j' is protected within this context
6 | (void) y.j;
| ~~^
t.C:12:7: note: declared protected here
12 | int j;
| ^

The trunk no longer ICEs. Also note that it's rejected by clang++. Removing
gcc-14 regression marker.
