I've tried this on XAMPP with PHP 7.0 back in time. Now tried to install newest version of XAMPP with PHP 7.1 and enabling opcache. SAME THING!!!!
Have to freakin idea how to manage with this. On almost every page refresh, XAMPP is restarting with an alert:
child process XXX exited with status 3221226356 -- Restarting
