To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report.

The Windows Event Viewer displays an error code 0xc0000005. In fact, this error only occurs one time each month for a year and a half. When updates are installed from Windows Update after the Patch Tuesday, the server is rebooted automatically and it is at this moment that the error concerning OPCache occurs. I think there is a problem during the shutdown of active processes. Visibly, I do not have other OPCache errors the rest of the time. I have catched a few full dump files for this crash and ericsten has exported for me (thanks to him) the two below backtraces. Perhaps this bug is linked to #69067 ? Hope this will help you to make a fix.
