Crash with opcache_reset() under high load in fpm

[nielsdos]

Description

The following code:

<?php
class T {
}

new T;
opcache_reset();

Executed under php-fpm with the following fpm configuration (save this as custom.conf):

[global]
error_log = /dev/stderr

[www]
listen = 127.0.0.1:9000
pm = static
pm.max_children = 10

Ran using: valgrind ./php-fpm -F -y custom.conf with opcache enabled.

Put under load with: ab -c 24 -n 200000 http://localhost/index.php

Resulted in this output:

And some similar crashes, also got one crash on time in zend_accelerator_util_funcs.c in ZSTR_SET_CE_CACHE_EX(ce->name, ce, 0);.

But I expected this output instead:

Obviously not that
