Symfony version(s) affected: 4.4.7

Description
In the mentioned constellation (IIS + PHP 7.4) Symfony generates a "Bad file descriptor" notice. This is also documented here: https://bugs.php.net/bug.php?id=79166 and is created in the Logger.php in line 82.
Even though this was already mentioned on bugs.php.net, I wanted to report it here as well, because Symfony is currently not usable with this webserver and PHP 7.4.

How to reproduce
Run Symfony 4.4 with IIS and PHP 7.4 with APP_ENV=dev
