Bug #74342 [Opn->Dup]: Segmentation fault in zend_objects_store_call_destructors

Edit report at https://bugs.php.net/bug.php?id=74342&edit=1 ID: 74342 Updated by: requinix@php.net Reported by: tom60 at op dot pl Summary: Segmentation fault in zend_objects_store_call_destructors -Status: Open +Status: Duplicate Type: Bug Package: opcache Operating System: Debian Jessie 64 bit PHP Version: 7.1.3 Block user comment: N 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. Previous Comments: ------------------------------------------------------------------------ [2017-03-30 14:33:09] tom60 at op dot pl 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'.
