These uses of std::move are taking data out of a repeatedly-used state object, à la Rust's std::mem::take(). But move-constructing or move-assigning from an object does not guarantee that the moved-from object is equivalent to a default-constructed one, or even that the moved-from object will continue to function like a non-moved-from object of that type (only that the object remains "valid"). Assuming there's no differing custom allocator shenanigans at play, both libstdc++ and libc++ do leave moved-from std::map objects (and probably others) in an empty, well-behaved, default-constructed state, at the time of this writing. However the correct tool here is std::exchange(). Change-Id: I7cf76762a1b05a542b53fcd74be100646a6a6964
