Private report: N
New Comment:
This backtrace is basically the same as the other so I'm going to reopen that bug report.
It may be difficult but please try again to come up with a reproduce script. Maybe see if changing some opcache settings affects or even eliminates the segfault.

Description:
------------
I've attached a backtrace of a segmentation fault that occured on our production Apache server after calling opcache_reset(). The issue is not easily reproducible as it probably depends on the kind of requests being processed at the time Opcache is cleared.
Previously reported as: https://bugs.php.net/bug.php?id=72183
Actual result:
--------------
warning: .dynamic section for "/usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0" is not at the expected address (wrong library or version mismatch?)
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Core was generated by `/opt/apache2/sbin/apache2 -k start'.
Program terminated with signal SIGSEGV, Segmentation fault.
