We observe regular segfaults on Ubuntu 14.04 LTS with Apache and PHP in
its default packages presenting these backtraces in a Coredump file:
#0 0x7f9911e619ad in zend_stack_push (
stack=stack@entry=0x7f9912627ca0 ,
element=element@entry=0x7f9912627c78 ,
size=size@entry=40) at /bui
The bug is instantly reproducible on a fresh Ubuntu 14.04.
Install server.
apt-get install apache2 php5 netcat
Setup a small PHP script with output in /var/www/html/
For Example as test.php
shutdown Apache service:
apache2ctl stop
Disable opcache with semicolon in front in
/etc/php5/apache2/co
This is hopefully the proper place for resolution of this bug.

The root cause of the problem has been determined to lie with the
apache2handler for PHP. It is not sufficiently up to date to function
well with Apache 2.4 receiving pipelined requests. A patch for the most
common setup has been developed, but it has not yet been integrated
upstream.

apache2.4 mod-php5.5 random segmentation faults in zend_stack_push()
Apologies, I didn't realise I was writing in Dutch :-)
The PHP project has released a fix for this problem with my cleanup
patch. It has been released with 5.6.28 and 5.5.24. It is also part of
an Ubuntu security release: http://www.ubuntu.com/usn/usn-2572-1/
