Ah, I managed it. I have the core dumps now.
You forgot to mention that I have to adjust /etc/php5/fpm/pool.d/www.conf with
a higher value than zero, i.E. rlimit_core = 10
I have 10 core dumps, all 119 MB large. How can I attach them here or hand them
over to you?

Thank you but I am unable to create a backtrace on my server.
I have set /proc/sys/kernel/core_pattern with
echo "/var/cores/core-%e.%p" > /proc/sys/kernel/core_pattern
Then I made /var/cores/ writeable for user www-data and chmodded it with 777.
Then sudo service php5-fpm restart and reloaded the page. It crashed but no
core was dumped. Why? ulimit is unlimited.
By the way, I am on nginx. Your instructions are for Apache.
