Probably broken while fixing 66721 or 67118

I think the 5.3.0-5.3.5 behaviour is correct: $this exists but has no properties set.

Test script:
---------------
<?php

set_error_handler(function($errno, $errstr){ throw new Exception($errstr);});

class DateTimeCustom extends DateTime
{
	public function __construct($datetime, $timezone = null)
	{
		try
		{
			parent::__construct($datetime, $timezone);
		}
		catch (Exception $e)
		{
			var_dump($this);
		}
	}
}


$date = new DateTimeCustom('sunday 09 september 2001 103:46:40 CEST');

Expected result:
----------------
object(DateTimeCustom)#2 (0) {
}

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