Previous Comments: [2012-10-18 08:53:06] larue...@php.net I'd like mark this as a critical one, any usage of zval_dtor with recursive array may trigger this segfault. but I can not find a way to fix this without inconsistent field. for now. thanks [2012-10-18 08:44:02] larue...@php.net the fix is not right for non-debug mode, we need find another way out.

still can not reproduce it,
php at wallbash.com , could you give me a access to your testing box? that
will
be useful.. :)
[2012-09-11 14:28:16] php at wallbash dot com
Fixed reproduce instructions: https://gist.github.com/3690351; Maybe that helps
you laruence.
I've misspelled the phpunit mock object dependency and it doesn't work with
newer versions (as it, i assume, involves object cloning that newer versions
have turned off). Any other minor versions don't lead to the segfault.
@reeze,

Hi wallbash,
when you got a backtrace, you could source php-src's backtrace of php script
gdb > source path/to/php-src/.gdbinit
gdb > zbactrace
then you may see a php level script, then we could find where cause the php
crash
