Coroutine inside a task makes worker crash

[vianeostech]

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

   
   I created this simple script to be able to create a coroutine inside a server task.
   *******
   <?php
   $server = new OpenSwoole\Server("127.0.0.1", 9501, OpenSwoole\Server::SIMPLE_MODE);
   $server->set( [ 'worker_num' => 1,
                    'task_worker_num' => 1,
               'task_enable_coroutine' => true ]);

$server->on('Receive', function (OpenSwoole\Server $server, $fd, $reactorId, $data) {

$server->task("taskcallback", -1, function (OpenSwoole\Server $server, $task_id, $data) { echo 'starting task' . PHP_EOL; });

});

$server->on("Task", function(OpenSwoole\Server $server, OpenSwoole\Server\Task $task ) { var_dump($task); Co::run(function() { Co::sleep(1); // } }); });

---

When I telnet localhost 9501 the program crashes.

2. What did you expect to see?

I expect the coroutine inside the task to make a sleep and exit

3. What did you see instead?

program crashes with the following error :

You can also try the following OpenSwoole support channels:

• Documentation - Documentation for Open Swoole
• Slack - Slack channel of Open Swoole
• Discord - Discord server of Open Swoole

Should no use co::run in the callback, but you can try to use go.

At least the worker does not crash anymore and the content of go is running properly.

Thank you :-)
