A copy of a concurrent bounded queue object doesn't preserve capacity of the original object

[SergueiEK]

Summary

A copy of a concurrent bounded queue doesn't preserve capacity of the original queue object.

Version

2021.10.0

Environment

gcc 13.1.0

Observed Behavior

If I set capacity to an instance of concurrent bounded queue and then make a copy of this queue, capacity of the copied object is set to the default value (0x3fffffffffffffff)

Expected Behavior

I would expect the copy of the queue having the same capacity as the original one.

Steps To Reproduce

The following code can be used to reproduce the issue:

#include <iostream>
#include <tbb/concurrent_queue.h>
int main(int ac, char**av) {
    tbb::concurrent_bounded_queue<int> q;
    q.set_capacity(100);
    std::cout << "q capacity = " << q.capacity() << std::endl;
    tbb::concurrent_bounded_queue<int> q2(q);
    std::cout << "q capacity = " << q.capacity() << " q2 capasity = " << q2.capacity() << std::endl;
}

It produces the following output:

q capacity = 100
q capacity = 100 q2 capasity = 4611686018427387903
