PHP Segmentation Fault

How Shlink is set-up

• Shlink Version: 3.2.1
• PHP Version: tried 8.1.9 and 8.1.10
• How do you serve Shlink: Self-hosted nginx
• Database engine used: MariaDB

Summary

When I open https://<domain.tld>/, it returns error "Bad Gateway 502".
The PID of the php-fpm pool that nginx uses will change every time I open https://<domain.tld>/

When I host it with php -S, it returns segmentation fault.

[root@server public]# /opt/alt/php-fpm81/usr/bin/php -S 0.0.0.0:8080

[Wed Sep 14 17:30:47 2022] ***.***.***.***:64519 Accepted
Segmentation fault

The browser displays "Error Empty Response"

Meanwhile, if I create a php file containing <?php phpinfo(); in the public folder, nginx can display the php info page properly when I open that page.

What can cause this issue and how can I fix it? Thank you.
