Bug Description
There is a segmentation fault in Zend OPcache. It is quite hard to reproduce. We experience it on a Magento server with a specific piece of code enabled, that deals with image resizing. Unfortunately, I don't have the code at hand, but I'm not sure it is relevant.
Backtrace looks like this:
