Segmentation fault (core dumped) while using `Server::tick()` or `Timer::tick()` with `Server::stats()`

What did you do? If possible, provide a simple script for reproducing the error.

I came up this error everytime, I'm not sure why.

<?php

use OpenSwoole\Server;
use OpenSwoole\Timer;

$server = new Server('0.0.0.0', 9500);

// $server->tick(2000, function() use ($server) {
//  print_r($server->stats());
// });

Timer::tick(2000, function() use ($server) {
    print_r($server->stats());
});

$server->on('Receive', function(Server $server, $socket, $fromId, $data) {
    print_r($data);
});

$server->start();

Output is:

$ php server.php 
Segmentation fault (core dumped)

2. What did you expect to see?

Stats of the server every 2 seconds.

3. What did you see instead?

For our production code, I just added dirty way of connecting to server saving stats to the database and closing connection. Cron is the responsible instead of OpenSwoole's timer.

4. What version of OpenSwoole are you using (show your `php --ri openswoole`)?

22.0.0

5. What is your machine environment used (show your `uname -a` & `php -v` & `gcc -v`) ?

It's not about the my own computer it's common for every machine: Linux fedora 6.4.11-200.fc38.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Aug 16 17:42:12 UTC 2023 x86_64 GNU/Linux
