Description:
------------
that below is a simplified version of our 'opcache.preload' with no active code

our build-environemt is calling 4 cli scripts and a forground httpd using the same php.ini under the same user  and global_preload_msg() is called multiple times with an arbitary string for $preload_file

sometimes this happens only one time, sometimes every start of a cli-script triggers global_preload_msg()

in normal operations the function receives the return value of opcache_compile_file and the full path compiled file

besides that strange calls of global_preload_msg() everything is working fine meaning all invocations of the cli-scripts and the webserver are logging success for each expected call of opcache_compile_file()

so the question why global_preload_msg() is executed at all even when the 'opcache.preload' only contains the function itself which so couldn't fire

for now i wrapped a file_exists() around the whole function code to silence it

that is pretty new and didn't happen with older git-snapshots

Test script:
---------------
<?php declare(strict_types=1);
function global_preload_msg(string $preload_file, bool $status): void
{
 if($status === FALSE )
 {
  switch($status)
  {
   case TRUE:  $status_out = 'OK'; break;
   case FALSE: $status_out = 'FAILED'; break;
  }
  error_log("PHP-PRELOAD " . strtoupper(PHP_SAPI) . ": $status_out '" . str_replace(__DIR__, '', $preload_file) . "'");
 }
}
?>

Expected result:
----------------
empty error log

Actual result:
--------------
error_log after the code-coverage run:
