Can't reproduce the segfault.
It doesn't output anything, but doesn't segfault too.

In fact, this code segfault if you add :

"var_dump($db);" before "echo $db;"

Without the var_dump, "echo $db;" prints nothing.

Description:
------------
The following code segfaults.

Reproduce code:
---------------
<?php
class FIIFO {

        public function __construct() {
                throw new Exception;
        }

}

class hariCow extends FIIFO {

        public function __construct() {
                try {
                        parent::__construct();
                } catch(Exception $e) {
                }
        }
        
        public function __toString() {
                return "Rusticus in asino sedet.";
        }

}


$db = new hariCow;

echo $db;
?>

Expected result:
----------------
No segfault but something like that:

Rusticus in asino sedet.

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