Description:
------------
When creating an instance of a class which tries to access a non-
existent parent in the class definition it throws an error on the 
file/line where the class is instantiated while i would assume it 
should be thrown where the error occurs, ie where the class tries to 
access its non-existent parent.

Reproduce code:
---------------
<?php
class myclass
{
	public $foo = parent::BAR;
}
new myclass();
?>

Expected result:
----------------
Fatal error: Cannot access parent:: when current class scope has no 
parent in /my/file.php on line 4 (the line which refers to the non-
existent parent)

Actual result:
--------------
Fatal error: Cannot access parent:: when current class scope has no 
parent in /var/www/html/swish/trunk/bug.php on line 6 (the line which 
creates the instance of myclass)
