I just would like to know what's the standard-defined behaviour when doing a push_back() on a std::deque.

The answer is, yes, it does invalidate _all_ iterators. However, unlike insertion into the middle of a deque, insertion into either end does not invalidate the references to elements in the deque (the Standard, 23.2.1.3).

Victor, did you just contradict yourself? The OP asked about a push_back (ie: insertion to the end of the deque), then you answered that it does invalidate all iterators, but not if you insert into either end.

Victor, did you just contradict yourself? The OP asked about a push_back (ie: insertion to the end of the deque), then you answered that it does invalidate all iterators, but not if you insert into either end. Please reread my answer. Iterators and references are NOT the same thing.
