Description:
------------
Function defined() is very strict whether class constant is checking. Non-declared (and not-autoloaded) class can be rather expressed as FALSE than fatal error.

Reproduce code:
---------------
var_dump( defined('Test::VALUE') );

Expected result:
----------------
FALSE

Actual result:
--------------
Fatal error: Class 'Test' not found

It seems this bug exists only in 5.2.x branch (since 5.2.4 - 5.2.9). PHP 5.3.0beta1 which is older than 5.2.9 is not affected.
