Summary: Preload: double free or corruption crash
Status: Feedback
Type: Bug
Package: opcache
Operating System: Centos 7.3
PHP Version: 7.4.2

Private report: N
New Comment:
Correct, changing from opcache.preload_user=username to opcache.preload_user=root fixes the problem.
Thanks!
Why do the docs say "Preloading code as root is not allowed for security reasons. This
directive facilitates to let the preloading to be run as another user."

Do you make use of opcache.preload_user? If so, this might be bug #79128.

Seeing the same issue on 7.4.2.
The error will appear only after certain number of classes loaded. If I remove one class, I can load
another.

I've cloned the zf1 repo and used your preload.php (with Redis commented) with the following
command:
~/php-7.4/sapi/cli/php -c ~/php-7.4/php.ini -d opcache.preload=preload.php -S localhost:8000 -t
demos/Zend/Wildfire/public/ -d include_path=$PWD/library
I couldn't produce a segfault that way (but I only used demos/Zend/Wildfire/public because it
was bundled and looked like web code...)

Still crashing in 7.4.1 RC1
I can prepare a very basic web application with ZF1 if you need it and send you wherever you want.
Meanwhile, this is a small preload file content im using that its working. If you uncomment the
block of Zend/Db classes it will crash when trying to load the site (when executing bootstrap) (at
least in my case)

Putting this back to Feedback. We've fixed quite a few preloading bugs in the last week, would
be great if you could recheck whether things are working now.
