I seem to recall back when concurrent_priority_queue was first released I had a very serious bug which I think was caused by some behaviour where items of the same priority were not processed in fifo order, something I did not expect.
Is this still the case? Was it ever the case?

Is there a TBB thread related to this?

I remember a problem related to priorities with 'tbb::task::enqueue' and it looks like a solution was found. I will find that thread some time later.
I don't remember if there was a thread related to it. It was quite a while back.

Here it is:
Forum topic: Tasks with priority execution order

And two more TBB threads related to priorities:
Forum topic: Assigning a priority to a task/algorithm

Forum topic: Problems with Enqueued Tasks in TBB v4.0 - Tasks Not Executed ( No Output )

I assume then that the order of elements of the same priority in a concurrent_priority_queue are indeed produced in a fifo order?
