Description:
------------
I had the following error message in my OpCache error log:
"Base address marks unusable memory region. Please setup opcache.file_cache and opcache.file_cache_callback directives for more convenient Opcache usage
Attempt to access invalid address."

I was wondering if this is a typo, because no such directive as "opcache.file_cache_callback" is mentioned in the documentation here:
http://php.net/manual/en/opcache.configuration.php

There *is* a directive called "opcache.file_cache_fallback", however...

Test script:
---------------
n/a
