)

No, it's just the default PHP installation from http://snaps.php.net,
php_info() says it's 4.3.6RC3-dev but i've seen this bug since i
upgraded to 4.3.5 from 4.3.4.



Here's my installation config:



'./configure' '--with-apxs2=/usr/local/apache2/bin/apxs'
'--disable-cgi' '--enable-safe-mode' '--with-openssl' '--with-pear'
'--with-zlib' '--enable-bcmath' '--enable-calendar'
'--with-curl=/usr/local/curl' '--enable-dba' '--enable-dbase'
'--with-dom=/usr/local' '--with-dom-xslt=/usr/local'
'--with-dom-exslt=/usr/local' '--enable-ftp' '--with-gd'
'--with-jpeg-dir=/usr' '--with-png-dir=/usr' '--with-ttf=/usr'
'--enable-gd-native-ttf' '--with-mcrypt' '--with-mhash' '--with-mysql'
'--enable-wddx' '--enable-xslt' '--with-xslt-sablot=/usr/local'
'--enable-exif' '--with-freetype-dir=/usr/local' '--with-xmlrpc'

Do you have the zend optimizer running?? = there are known problems
with this.

The warning PHP prints is the following: 



Warning: String is not zero-terminated
(ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ�̏*) (source:

Description:
------------
Overloading a class called 'Configuration' tends to segfault on 4.3.5,
4.3.6RC1 & 4.3.6RC3 (snaps.php.net). 

Reproduce code:
---------------
class Configuration {

        

        var $elem = Array();

        

        function elements() {

                return $this->elem;

        }

        

        function __get($prop_name, &$prop_value) {

                if(isset($this->elem[$prop_name])) {

                        $prop_value = $this->elem[$prop_name];

                        return true;

                } else {

                        return false;

                }

        }

        

        function __set($prop_name, $prop_value) {

                $this->elem[$prop_name] = $prop_value;

                return true;

        }

}

 

overload('Configuration');



$_CONFIG->db_type = 'mysql';

$_CONFIG->db_host = 'localhost';

$_CONFIG->db_user = 'user';

$_CONFIG->db_password = 'passwd';

$_CONFIG->db_name = 'database';



cause's segfault & abnormal termination of script.



Expected result:
----------------
No output, just storing the called fields in an array & being able to
fetch those values in the same manner as i've stored them using
overloading.

Actual result:
