Sorry for my error, I have also the crash on PHP 5.6.34. I will keep you informed about the response of the ioncube support. Greetings. Previous Comments: ------------------------------------------------------------------------ [2018-04-18 17:44:41] cmb@php.net Thanks for further investigation! Since this *may* be an ionCube issue, I suggest to contact them. Anyhow, I have to bail out here, since I'm neither an engine guru, nor accustomed to ionCube. ------------------------------------------------------------------------ [2018-04-18 17:21:39] 1978 dot jl at gmail dot com Hi Christoph, after analyze with DebugDiag, the cause should be in a ioncube module (ioncube_loader_win_5.6.dll), the source code that cause this stack overflow seems to be : $property = null; // bad case $p = $my_object->$property; // seems to crash only when used in ioncube context, seems no crash if ioncube deactivated But I don't understand why this crash not appear on PHP 5.6.34 in same conditions. Greetings. ------------------------------------------------------------------------ [2018-04-18 13:18:19] cmb@php.net Okay, I was asking for a reproduce script, since the backtrace is not particularly helpful ("Stack unwind information not available. Following frames may be wrong."), and since the stack overflow might be caused by deep (infinite?) recursion in the userland code. Can you provide a debug backtrace[1]? Also note that PHP 5 will not receive normal bugfixes anymore, but only security fixes. So unless it can be shown that this issue is indeed a security issue, we won't fix it for PHP 5, so it might be best if you test the project under an actively supported PHP version[2] if possible.

Greetings. ------------------------------------------------------------------------ [2018-04-18 12:27:12] cmb@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with , is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
