Description:
------------
I am testing the new preloading feature but it still doesn't work. If i run the built in web server with the following command:

php -dopcache.preload="/projects/PED/NutriBees/var/cache/prod/srcApp_KernelProdContainer.preload.php" -dopcache.enable=1 -S localhost:8090

I get this output:

Some issues related to preloading with Symfony will only be resolved in 7.4.2. It's hard to say whether the problem you're seeing is one of those or something new.

[2019-12-19 14:18 UTC] n_avatar at mail dot ru

Have same problem.
Found that doctrine/persistence >=1.3 lead to "zend_mm_heap corrupted".
"doctrine/persistence": "^1.2 <1.3" - fine

[2019-12-19 14:42 UTC] nikic@php.net

This is likely related to class aliases added by Doctrine, in which case 7.4.2 should resolve the issue.

[2020-01-05 02:47 UTC] myaddressmail at gmail dot com

Same with Twig (without doctrine) => Zend_mm_heap corrupted at server startup

Without Twig (removed from the preloading) => it works

[2020-01-11 19:38 UTC] tobias dot nyholm at gmail dot com

I just tried in PHP 7.4.2RC1. I have the same problem. 

Im using OSX 10.15 and I tried preloading on a Symfony 4.4 application. I got the following output when trying to start PHP-fpm.

@anhchienhoang at gmail dot com: These warnings can be ignored. Or do you get a crash afterwards?

[2020-01-28 15:52 UTC] anhchienhoang at gmail dot com

@nikic I got crashes afterwards, php-fpm stop working.

[2020-01-28 16:05 UTC] nikic@php.net

@anhchienhoang at gmail dot com: Do you use opcache.preload_user? If you do, then the crashes are due to bug #79128.

[2020-01-28 16:48 UTC] anhchienhoang at gmail dot com

@nikic yes! I put www-data. Thanks for your info.

In a different application I got more `zend_mm_heap corrupted` errors. 
The application seams to be running fine, but having a corrupted heap is never fun. 

After disabling preloading, the error message went away. Ideally I'll provide you with a small reproducer, but I have not been able to create one. The application in question is open sourced and running on Symfony cloud.
