PHP version:      7.0.0RC8
Package:          PHP Language Specification
Bug Type:         Bug
Bug description:Segmentation fault (core dumped)

Description:
------------
I tried to run "composer update" in a Symfony2 project and got the
following error: "Segmentation fault (core dumped)". By setting
opcache.huge_code_pages=0 at /etc/php.d/10-opcache.ini the issue gets
fixed

Actual result:
--------------
(gdb) run /usr/local/bin/composer
Starting program: /usr/bin/php /usr/local/bin/composer
[Thread debugging using libthread_db enabled]
 
Program received signal SIGSEGV, Segmentation fault.
