Here's my take on it: a compiler is allowed to a remove any copy operations as long as the programs observed behavior is the same. AFAICT, copying (or assigning) a vector<int> (compared to not doing it) will never change the observed behavior.
You're kidding, right? I doubt very much that the compiler can legitimately decide that side effects on the memory subsystem due to allocation are not observable.
