Description:
------------
a script was returning an error that a developer defined function was missing.  after hours of debug, I turned off the cache and it worked fine.

since then I have repeated this experience.

the function is defined in an include that then includes the file that actually contains the function.  it seems that it is dropping the include.


Reproduce code:
---------------
require $_SERVER['DOCUMENT_ROOT']."/dynamic/common/lib/univ_func.php";

Expected result:
----------------
I expect it to include the file specified which declares the function(s).  I expect those functions to be able for use in the script.

Actual result:
--------------
No error about the include file not being found, but there is an error when the function(s)defined in the include file are called.
