Description:
------------
I'm using the prado framework (www.xisc.com)
for performance problems i made a script that aggregate namespaces in one file.

it seem that on really big files to include, like 400 or more KB:

class aaa extends bbb {}
class bbb {}

will not work, you need to:

class bbb {}
class aaa extends bbb {}

---
Class are missing some extended properties and methods... 
The missing prop/methods are in previous defined classes

like
require_once('filea.php');
require_once('fileb.php');
if a class defined in the fileb, BIG file, extends something defined in filea it will not work anymore.

i'm not sure but it can be also that it's due to:
file a:
class a {}
class b extends b {}
file b:
class c extends b {}
and we are missing class a prop and methods in class c.

Reproduce code:
---------------
i can give an ftp access to an installation of the code.
or a link to a zip to download

Expected result:
----------------
it should work, if we will not aggregate files it work perfectly

Actual result:
--------------
no error shown or logged we arror reporting all activated.

it display property or method not defined.
