--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Why should the compiler warn here? There are no resources being freed. Making
trivial copies and then destroying them is not a bug.
If you give the class some resources to manage (e.g. a pointer member) then
-Weffc++ will warn that you messed up:
dest.C:2:8: warning: ‘struct S’ has pointer data members [-Weffc++]
2 | struct S {
| ^
dest.C:2:8: warning: but does not declare ‘S(const S&)’ [-Weffc++]
dest.C:2:8: warning: or ‘operator=(const S&)’ [-Weffc++]
dest.C:5:10: note: pointer member ‘S::p’ declared here
5 | int* p = nullptr;
| ^
It would be nice if you could turn on this warning without the rest of -Weffc++
but that's PR 16166.
