Description:
------------
Using latest packages from the Ondrej Sury PPA, I get prod reproducible but never non-prod segfaults when making requests via the mod php7.1 apache module.


Below is a bt using the debug symbols deb the sury ppa publishes for mod php.

I've tried a number of things to get a local repro with no success, but prod traffic will consistently immediately cause the issue.

Setting opcache.enabled = false causes the issue to go away.

The php redis extension was producing almost the same symptoms, here is the ticket for that: https://github.com/phpredis/phpredis/issues/1088

Expected result:
----------------
No segfault ;).

Actual result:
--------------

Description:
------------
Using latest packages from the Ondrej Sury PPA, I get prod reproducible but never non-prod segfaults when making requests via the mod php7.1 apache module.


Below is a bt using the debug symbols deb the sury ppa publishes for mod php.

I've tried a number of things to get a local repro with no success, but prod traffic will consistently immediately cause the issue.

Setting opcache.enabled = false causes the issue to go away.

The php redis extension was producing almost the same symptoms, here is the ticket for that: https://github.com/phpredis/phpredis/issues/1088

Expected result:
----------------
No segfault ;).

Actual result:
--------------

I'm having this issue on PHP7.2 running on Ubuntu 16.04.4. When I restart apache the first request works and then every following request says its getting a 500 but if I disable opcache it works every time no problem. 

I tried blacklisting the files that make the call to the oauth library but it still fails.

Does this still happen with any of the actively supported PHP
versions[1] and latest oauth (2.0.7)?
