            Bug ID: 70766
           Summary: stream iterators, shared_lock, and atomic<T> should
                    all use addressof and not &
           Product: gcc
           Version: 7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rs2740 at gmail dot com
  Target Milestone: ---

1) istream_iterator and ostream_iterator's constructors and istream_iterator's
operator-> should use __addressof (this is LWG issue 2576).

2) shared_lock's constructors should use addressof (LWG issue 2577).
unique_lock's constructors already do that.

3) The primary atomic<_Tp> template uses & in many places where it should be
using addressof.
