This might be related to a segfault I'm experiencing. I have a repo with an example here: https://github.com/natewiebe13/php-preload-segfault

Description:
------------
It is possible to cause RTD key collisions through opcache. Here is a reproducer using file cache,
though the same would also work through SHM:

file1.php:
<?php
return function() {};

file2.php:
<?php
$file = 'file1.php';
var_dump(include $file);
touch($file);
var_dump(include $file);

Then run file1.php first and file2.php second under -d opcache.file_cache_only=1.

Actual result:
--------------
Fatal error: Runtime definition key collision for function {closure}. This is a bug
