I cannot reproduce memory issues with PHP 7.1.24. Is OPcache or
some other bytecode cache involved?

which proves that it is a bad idea include code in a loop

you can try this code, it's ok!
<?php
class A
{
}
while(true)
{
$a = new class extends A{};
usleep(1000);
}

what else do you expect when you include a file in and endless loop?
