Bug #78995 [Com]: opcache.preloading results in zend_mm_heap corrupted

Edit report at https://bugs.php.net/bug.php?id=78995&edit=1 ID: 78995 Comment by: tobias dot nyholm at gmail dot com Reported by: patrick dot fazzi at ped dot technology Summary: opcache.preloading results in zend_mm_heap corrupted Status: Open Type: Bug Package: opcache Operating System: Ubuntu 18.4 PHP Version: 7.4.1 Block user comment: N Private report: N New Comment: 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.
