--- Comment #2 from Dennis Lubert <plasmahh at gmx dot net> ---
Since someone else pointed out that there is a bug talking about duplicates
already, now how my real code is more like the following. Also note that it
warns when I remove the dtor of evr.

struct evr
{
        ~evr( );
};

struct evd
{
        virtual __attribute__((warn_unused_result)) evr rs( ) = 0;
};


class sd
{
        [[gnu::warn_unused_result]] evr callme( evd& );
};


evr sd::callme( evd& edis )
{
        edis.rs();
}
