Description:
------------
 - in php 7.4.5 with disabled cli (opcache.enable_cli=0) memory leaks and increasing execution time.

 - in php 7.3.15 with disabled cli (opcache.enable_cli=0) everything is ok.

In case with enabled cli opcache php 7.4 works as expected with no leaks. 

Test script:
---------------
<?php
$i = 0;

while ($i < 100000) {
    $checkpoint = ($i % 10000 === 0);

    if ($checkpoint) {
        $start = hrtime(true);
    }

    @include __DIR__ . '/unexistentfile';

    if ($checkpoint) {
        echo "time: " . (int)((hrtime(true) - $start)/1000) . " micro s    $i\n";
        echo "alloc mem: " . (memory_get_usage(true) / 1024 / 1024) . "Mb \n";
    }

    ++$i;
}


Expected result:
----------------
No memory leaks and constant execution time of each iteration

Actual result:
--------------
Memory leaks and increasing execution time
