New Comment:
I would have guessed someone would have run Laravel's phpunit test suite while and after
developing something as inner-touching as preloading.
Guess not! Probably didn't run Symonfy's tests either.

That is supposed to be "You will now get a fatal error [â¦]".

Support for class aliases has been added, and issues relating to classes with unresolved
initializers fixed.
You will not get a fatal error if you try to preload a class with unresolved initializers under the
"require" model (under the opcache_compile_file() model a graceful fallback is possible).
However, opcache will try harder to make sure everything can be resolved.
I was not able to test preloading Laravel due to https://github.com/briannesbitt/Carbon/blob/298d9f0e8e369301b0ca647f3ce9c92b53ad3a82/src/Carbon/Traits/Date.php#L541-L556.
This references constants that are not defined in the trait and are only available in the class
using the trait. This will need to either be fixed, or the trait and it's dependencies skipped.

I've tested preloading Laravel too, and i'm getting "zend_mm_heap corrupted"
with this script (https://github.com/brendt/laravel-preload/blob/master/preload.php) on a Docker
container (both require and opcache_compile_file options don't work).

Unfortunately I keep getting a segfault even when switching to opcache_compile_file() and restarting
php-fpm.
Wish I had more input to provide

We've found some fundamental design problems in the preloading functionality today ...
The tl;dr is that you need to use opcache_compile_file() based preloading for now. Preloading based
on require calls has a whole series of issues that may result in crashes.
