I've added two tests (bug45910.phpt, bug45910_2.phpt), the latter
segfaults. (5_3 and HEAD)

Here's a simple script based in your example:

class foo {
	const AAA = 'x';
	const BBB = 'a';
	const CCC = 'a';
	const DDD = self::AAA;

	private static $foo = array(
		self::BBB	=> 'a',
		self::CCC	=> 'b',
		self::DDD	=>  self::AAA
	);
	
	public static function test() {
		self::$foo;
	}
}

foo::test();

The error is only issued when BBB and CCC contains same value.

okay here a test script...
<?php
        class Test
        {
                const HOST_SK = 13;

                const NOSHOW = 'n77';

                const CONTENT_AD                = 'n10';
                const CONTENT_AD_MAIN           = 'n5';
                const CONTENT_AD_SALE           = 'n15';
                const SKYSCRAPER                = 'n4';
                const SITEBAR                   = 'n6';
                const BIGSIZE_BANNER            = 'n3';
                const CONTENT_USERPAGE          = self::NOSHOW;

                const HOCKEY1_SKYSCRAPER        = 'n4';
                const HOCKEY2_BIGSIZE_BANNER    = 'n3';

                const SPECIAL_FOTO_SKYSCRAPER   = 'n14';

                private static $host_matching   = array(

Description:
------------
The problem is that the same script worked in php5.2.6, but in php5.3
it results in a "Fatal error: Cannot declare self-referencing constant
'n61' in ..."

There is an array that uses many constants to set the array with
values. If I execute a method of the class this error message stops the
execution..but the line of the code has nothing todo with this array!
strange error... just let me send my test code, u will see it yourself.
If i modify the array, remove the lines that php is complain about,
some lines and so on.. it works.. but these lines are not differnt to
the ohter lines..!? I don't understand it.

Also tried with latest cvs snapshot

Reproduce code:
---------------
I have a test script, but I don't wanna publish the code... May I send
it directly to a php developer?

Expected result:
----------------
like in php5.2.6 this code should work!

Actual result:
--------------
Fatal error: Cannot declare self-referencing constant 'n61' in
/..../test.php on line 132
