Bug description:  xml_parse cause segmentation fault when xml_set_object called from 
class method

Description:
------------
xml_parse cause segmentation fault when xml_set_object called from class
member function (as showed in example below). When xml_set_object called
from class constructor or from "parse" class method then things going ok,
but when xml_set_object placed in "init" class method then things going
wrong.

Reproduce code:
---------------
<?php



class sxml {

    var $handle;



    function start_elem($parser,$name,$attribs) {

        print "$name ";

    

        foreach($attribs as $key => $value) {

            print "$key = $value ";

        }

        print "\n";

    }



    function end_elem()

    {

    }



    function init() {

        $this->handle = xml_parser_create("ISO-8859-1");

        xml_set_object($this->handle, $this);

        xml_set_element_handler($this->handle,'start_elem','end_elem');

        xml_parser_set_option($this->handle,XML_OPTION_CASE_FOLDING,0);

    }



    function release() {

        xml_parser_free($this->handle);

    }



    function parse($source) {

        $this->init();

        xml_parse($this->handle, $source);

        $this->release();

    }



}



$source = '<OBJECT>

<CLIENT_ID>1</CLIENT_ID>

<CLIENT_CAT_ID>3</CLIENT_CAT_ID>

<USER_ID>1</USER_ID>

<GROUP_ID>2</GROUP_ID>

<SESSION_CODE>6f121f896c1db735891d28448b02b978</SESSION_CODE>

</OBJECT>';



$obj = new sxml;

$obj->parse($source);



?>



Expected result:
----------------
OBJECT

CLIENT_ID

CLIENT_CAT_ID

USER_ID

GROUP_ID

SESSION_CODE

Actual result:
--------------
Segmentation fault
