--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Confirmed.  Started with r6-6830-g20a0c6f9bdbd78:

commit 20a0c6f9bdbd781ed5d413a10a06764a174dc394
Author: Patrick Palka <ppalka@gcc.gnu.org>
Date:   Mon Feb 8 23:02:50 2016 +0000

    Fix PR c++/69283 (auto deduction fails when ADL is required)

but reverting that fix doesn't make the ICE go away.=
