Ok, I think the original commit just surfaces a lingering bug in `ConcurrentQueue`. `UnsyncFront` is simply not safe, as it calls `deque::front()` which can be implemented in terms of `deque::begin()`, but a concurrent call to `deque::push_back()` is specificed as invalidating all iterators. -- This is an automated message from the Apache Git Service.
