Description:
------------
When preloading any class in ZTS, a segfault occurs on shutdown.
Version is 7.4.10 @ 81e31eff0bc570155070183bd857b3f238ad3af6
 compiled from source on Ubuntu 20.04, compiled with

`./configure --disable-all --enable-cli --enable-maintainer-zts --enable-opcache --enable-debug`

Ran with
`valgrind sapi/cli/php -dzend_extension=$(pwd)/modules/opcache.so -dopcache.enable_cli=1 -dopcache.preload=preload.php -v`

Test script:
---------------
preload.php:
<?php

class SomeClass{}

Expected result:
----------------
The version output should be produced, without any segfault, something like the following:
