--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> ---
(In reply to DB from comment #10)
> Sorry to pester, but is this likely to get anywhere, any time soon?

No, probably not. Comment 2 doesn't work because -Wsystem-headers can't be
enabled and disabled using pragmas. It doesn't work like other warnings.

I don't think this can be fixed in the library.


> I presume the same goes for std::shared_ptr, too.

No, because shared_ptr type-erases the deleter and so deletes the dynamic t=
ype
even if the stored pointer is upcast to a different static type.=
