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;
?>

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;
?>
