 New Comment:

I encounter this bug with builds of 5.2.8, built on debian.

Configure Line:
 Command        './configure' '--with-apxs2=/usr/local/apache2/bin/apxs'
'--with-mysql' '--with-gd' '--enable-soap' '--with-libxml-dir=/usr/lib/'
'--with-mysql-sock=/tmp' '--with-tidy' '--with-jpeg-dir=/usr/lib/'
'--with-xsl' '--with-curl' '--with-snmp'
'--with-freetype-dir=/usr/local/freetype2' '--with-zlib'
'--enable-gd-native-ttf' '--with-openssl'
'--with-mm=/usr/local/mm-1.4.2/' '--with-mcrypt' '--with-pdo-mysql'
'--with-mysqli' '--enable-debug'

"memcheck" output is up at
http://example.preinheimer.com/30707.a.txt
(too long to paste to a form)

Please let me know if there's anything I can do to help diagnose the
issue.

Same bug, different code.
two hours lost :(

The constructor contains a return statement, but it is only 

<?php

class UserModuleTest  {
        
        public function __construct($obj) {

                try {
                        new UserModuleTest($this->query());
                } catch(Exception $e) {
                }
                
        }

        public function query() {
                throw new Exception;
        }



}

$test = new UserModuleTest(new UserModuleTest());

?>

This code is much simplier IMO and demonstrates the same behaviour
(both with 5.0.x & 5.1.x):
<?
class C {

        public function __construct() {
                $this->byePHP($this->plip());
        }

        public function byePHP($plop) {
                echo "www.haricow.org";
        }

        public function plip() {
                try {
                        $this->plap($this->plop());
                }
                catch(Exception $e) {
                }
        }

        public function plap($a) {
        
        }

        public function plop() {
                throw new Exception;
        }

}

new C;
?>

Description:
------------
I get another segmentation fault... 
You can look at the reproduce code. 

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

class B {

        public function plip() {

                try {
                        $this->plap($this->plop());
                }
                catch(Exception $e) {
                }

        }
        
        public function plap($a) {
        }
        
        public function plop() {
                throw new Exception;
        }
        
}

class C {

        public function __construct() {

                $b = new B;
                $this->byePHP($b->plip());

        }

        public function byePHP($plop) {
                echo "www.haricow.org";
        }

}

new C;
?>

Expected result:
----------------
www.haricow.org 

Actual result:
--------------
