Hello, I would like to propose an RFC for the way references are currently handled inside of the Zend Engine. I have a somewhat detailed write up here http://stackoverflow.com/questions/26081106/assign-by-reference-bug and someone else wrote up this blog post on this issue here http://blog.adamcameron.me/2014/09/php-looking-at-some-interesting.html.
Thanks, Michael Schuett
