Description:
------------
This is a copy of bug #35156, which is closed...

The code there still segfaults with php4-STABLE-200511160748 (combined with at least Apache 2.0.54/.55).

I disabled Zend Optimizer, no change.

I've put ob_* functions now into 'disabled_functions' and the logs (Shared Hosting Server) remain free from Segmentation faults.

Reproduce code:
---------------
(taken from bug #35156)

<?php 
function nooutput($text) { return ""; } 
print "Before\n"; 
ob_start("nooutput"); 
print "Middle\n"; 
ob_flush();
ob_end_flush(); 
print "After\n"; 
?> 

Expected result:
----------------
(taken from bug #35156)

Before
After


Actual result:
--------------
Apache child Segmentation fault

[Thu Nov 17 11:08:59 2005] [notice] child pid 4657 exit signal Segmentation fault (11)
