Fatal error: Uncaught FiberError: Cannot suspend in a force-closed fiber

[EdmondDantes]

Sometimes, I encounter an error of this kind.

Environment:

PHP 8.3.4 (cli) (built: Mar 13 2024 11:43:12) (ZTS Visual C++ 2019 x64)

Unfortunately, I can’t identify a clear pattern to reproduce this issue.
I’ve looked into the PHP Fiber code a bit and found that the situation occurs if a Fiber is destroyed in a destructor. However... for some reason, the code involving it continues to execute even after the destructor has been called.

I understand that this is a challenging case to capture. So far, I can’t provide more information. I tried to understand the situation through step-by-step debugging, but… I didn’t see anything suspicious. If I could catch the moment when the Fiber destructor is called and see why the code continues after that, I could easily pinpoint the problem. But I don’t know how to catch the destructor call point.

Maybe you know something about this issue. Thank you!

Error occured here:
Revolt\EventLoop\Internal\AbstractDriver

unset($callback, $args);

            if ($this->interrupt) {
                /** @noinspection PhpUnhandledExceptionInspection */
                \Fiber::suspend($this->internalSuspensionMarker);
            }

May be a memory corruption issue, encountering similar issues as well.
