as a first option, could you please install (on testing machine where you can reproduce the error), update PHP from here: https://packages.sury.org/php5-5.6/ and also install php5-dbg package. Then try reproduce the error again. If you are successful it might be worth reporting the crash to upstream bug tracker here: https://bugs.php.net/ using instructions here: https://bugs.php.net/how-to-report.php as you are the one who can reproduce the issue, so it's best if you have a contact with upstream developers directly.
