Bug description:php_zval_filter_recursive segfault
Description:
------------
Hi:
php_zval_filter_recursive segfaults once in a while, with the following
backtrace
Test script:
---------------
Program terminated with signal 11, Segmentation fault.
#0 0x00007fb81e3a58a2 in php_zval_filter_recursive (value=0x7fb823d86768,

(gdb) bt full

element = 0x0
pos = 0x7fb823d86790
#1 0x0000000000000000 in ?? ()
Im not familiar with the code so Im not sure if checking element != NULL is
a correct fix.,
Expected result:
