Description:
------------
After updating our php code (added some classes, have rewritten some functionality) one of our utilites stopped to work. After deep digging we found that php doesn't define a class in some circumstances. In attachment is our handmade example.
Try to run file0.php

On 5.2.17 and 5.3.2 we have output:

/home/vitaly/.../public_html/file3.php
/home/vitaly/.../public_html/file4.php
/home/vitaly/.../public_html/file2.php
/home/vitaly/.../public_html/file1.php
/home/vitaly/.../public_html/file0.php

On 5.3.5:

Fatal error: Class 'Class1' not found in /.../file3.php on line 6

On our real project (which uses 5.2.17) ^^ we have the same fatal error. Project is very big and has many includes, so we can't provide simple example for it, but probably changing example from attachment to one or another side will do the trick..

We don't have 5.3.6 version, yes, we out of date, but I think this is something that's will reoccur from one version to another.

Expected result:
----------------
Run file0.php

I expect to have loading sequence



Actual result:
--------------
On some php version I have fatal error that class is undefined.

No idea what might have been wrong with your 5.3.5, but it works fine on 5.3.10 
and 5.4.0. I get the same output from both:

/home/rasmus/file3.php<br/>
/home/rasmus/file4.php<br/>
/home/rasmus/file2.php<br/>
/home/rasmus/file1.php<br/>
/home/rasmus/file0.php<br/>
