Description:
------------
Trying to set a value in a loaded xml file, it returns a seg fault in the log. So I ran gdb.

Reproduce code:
---------------
$s = simplexml_load_file('security.xml'); // $s->security[2]->id = 20

$s->security[2]->id = 21;

Expected result:
----------------
It should set that value to 21 from 20.


Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.

Can you please also add the output from "bt" from the GDB command line? (That will generate the backtrace)
