Description:
------------
The Exception implementation appears buggy under Win XP with Apache 2. When the reproduce code is run a couple of time by refreshing the browser (IE 6 SP2), Apache 2 crashes.

Log book entries:

Crashed application: Apache.exe, version: 2.0.48.0, 
Crashed module: php5ts.dll, version: 5.0.0.0,
Crashed upon: 0x0003d0ba.


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

class UserException extends Exception {
	public $message;

	public function __construct ($message) {
		$this->message = $message;
	}
}

try {
	throw new UserException("Unknown error");
} catch (UserException $ue) {
	echo "Error: $ue->message, at line: ", $ue->getLine(), " in file: ", $ue->getFile();
}

?>

Expected result:
----------------
Error: Unknown error, at line: [...] in file: [...]

Actual result:
--------------
Crash of Apache 2 after a couple of reloads
