   Hi,

   At first time, it was a bug in the useful xdebug, and I follow it to 
the PHP code <http://bugs.xdebug.org/bug_view_page.php?bug_id=0000340>.

   When exception::$message, exception::$line are not of the initial 
type, it segfaults (for strings) or display non-predictible data. The 
next snipset for test :

<?php

class my_file
{
         public  function __toString()
         {
                 return "somebuildfilename" ;
         }
}

class my_exception extends exception
{
         public  function __construct()
         {
                 $this->message = new stdclass ;
                 $this->file = new my_file ;
                 $this->line = "12" ;
         }
}

throw new my_exception ;

?>

   I attach a patch that correct the segfault. Diff was produced with 
this line : diff php5.3-200808141030{,-lupus}/Zend/zend_exceptions.c

   Regards, Mickaël.
