Bug #70665 [NEW]: invalid pointer: 0x00007f6a283ff0e0

From: admin at thecustomizewindows dot com Operating system: Ubuntu 14.04.3 LTS PHP version: 5.5Git-2015-10-08 (Git) Package: FPM related Bug Type: Bug Bug description:invalid pointer: 0x00007f6a283ff0e0 Description: ------------ It is opened as bug for possible future reference only. It occurred after running command to get php-apc installed after enabling Zend OpCache from php.ini for emulation of our one blog reader's problem. Other packages were - php5-xcache and php5-apcu. php -v command vanished xcache's name in output and zend opcache pointed towards an invalid pointer error. We have added a PHP script to get 500 internal server error. Setup with such wrong steps will work fine, but possibly it is a risk to allow such unnoticed error. Unexpected output : ############## root@4gbtcw:/home/ubuntu# php -v PHP Warning: Module 'Zend OPcache' already loaded in Unknown on line 0 PHP Warning: Zend OPcache: module registration failed! in Unknown on line 0 PHP 5.5.9-1ubuntu4.13 (cli) (built: Sep 29 2015 15:24:49) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies *** Error in `php': free(): invalid pointer: 0x00007fb8003ff0e0 *** Aborted (core dumped) ############## Test script: --------------- repo has test.php file and backtrace - https://github.com/AbhishekGhosh/invalid-pointer-0x00007f75ec3ff0e0 Expected result: ---------------- test.php will show 500 internal server error on curl.
