Description:
------------
A error occured when I re-installed php
from 5.16 to 5.21.

The error message
'level too deep - recursive dependency? in Unknown on line 0'
occurs even such as short script.
<?php phpinfo();

I configured like this.


Reproduce code:
---------------

Expected result:
----------------
Other existing php script can't move usually.
About all show nothing because of error.



Actual result:
--------------
I read past logs like
http://bugs.php.net/bug.php?id=21333
http://bugs.php.net/bug.php?id=22482

but, there are no files in
extension_dir ( /usr/lib/php ) and
source dir ( /usr/local/src/modules )
in my case.

I home your help.
thankyou.
