--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Do you have a full example which shows the issue?
In your case does ReturnValue have a copy constructor?
If so this is a dup of bug 38172. Note C++17 defines [[nodiscard]] which
should be used here instead really but it is only implemented in GCC 7.
