Description:
------------
Bug #35264 was fixed, but this introduced a new Apache child segmentation fault, under some conditions.

With PHP 4.4.0 and below, the following would work correctly with Apache 2.0.54/.55 : 

AddOutputFilter INCLUDES .php
AddType application/x-httpd-php .php

Then having a .php that contains multiple (eg. 2) <!--#include virtual="/page.html" --> and for example about 24 thumbnails (of 4.0k each), you read a segfault of an Apache child process in the error_log and the page loading finishes and showing cut-off content.

Like I said, the segfault happens since the fix for bug #35264, before it just didn't segfault but stopped loading.

When changing output_buffer to 0 or Off, no difference.
Only when I set output_buffer => 16384 in php.ini, the page loads completely.

Strange thing here is that output buffering isn't used in the page at all, or SSI by default must use buffering...

Seems to me that something has changed regarding buffering between 4.4.0 <-> higher versions.

Like the memory get's full or so, cause when I delete a few lines of html-code in the page (random), it does load.

Noe that this does like an Apache bug or so, but hence it only happens since PHP 4.4.1

Reproduce code:
---------------
Hopefully, the description rings a bell at you guys :)
But possible if really needed.


Expected result:
----------------
Page loads completely (100%)

Actual result:
--------------
Page loads not completely
