Even if the element were returned by value, the following code would suffer from the race condition: element = my_conatiner.front(); // here -- the front element might already have been popped here by another thread! my_container.pop(); or: if (!my_container.empty()) { // the container might already be empty here! element = my_container.front(); } 2008/7/11, Khandelwal, Amit <amit.khandelwal@lehman.com>:
Agreed. I didn't realize that I had typed return by reference. My bad.
