What constitutes a valid state for a “moved from” object in C++11? http://stackoverflow.com/questions/12095048/what-constitutes-a-valid-state-for-a-moved-from-object-in-c11 state so you do have to check. For example you should not pop_back on a moved from string until you have queried the state of the.. state of the string to determine that the preconditions of pop_back are met. std string s foo std string t std move s if s.empty.. preconditions so it's safe to call on moved from objects s.pop_back after verifying that the preconditions are met pop_back is safe..
