Description:
------------
When running a compiled php file, a segmentation fault occurs.
Files compile okay but fail to run.
The segfault only happens when the Zend Optimizer is loaded.  When I comment out the extension, bcompiler runs as expected.
I am not sure if this is expected but I am posting this anyway since there was not mention in the manual pages or comments.
If this is an error in zend optimizer itself rather than bcompiler I apoligize for posting here.

Reproduce code:
---------------
<?php
include("out.phb");
?>

uncompiled version of out.phb
<?php
echo "BCOMPILER WORKED";
?>


Expected result:
----------------
BCOMPILER WORKED

Actual result:
--------------
Segmentation fault.

Thank you for taking the time to write to us, but this is not
a bug.

Currently, bcompiler doesn't work with Zend Optimizer. In my todo for bcompiler 0.9 there're some improvements to bcompiler that might resolve conflicts with Zend Optimizer.
