--- Comment #2 from François Dumont <fdumont at gcc dot gnu.org> ---
I'd like to take this one and already started working on it.

I've already many patches awaiting for the hashtable implementation but none
fixing this problem.

I also don't get the point about std::unordered_map performance issue on
64-bits platform. Maybe you should elaborate as part of another bug report.
