Failse positive accessMoved

[Anton Davidenko]

example:

    struct S
    {
        int i = 0;
        bool operator < (const S& rhs) const
        {
            return i < rhs.i;
        }
    } s;
    std::set<S> set1, set2;
    auto [it, inserted] = set1.emplace(std::move(s));
    if (!inserted)
    {
        set2.insert(std::move(s));
    }

Not sure about this one. According to https://en.cppreference.com/w/cpp/container/set/emplace, an element might be constructed (move-constructed in this case) even if no insertion takes place.
