The shortest working example:

<?php
 file_put_contents('8192_testcase.php',str_repeat(' ',8192));
?>
<a href="8192_testcase.php">run testcase</a>

Use Apache 2.2.21, PHP 5.*, Win 7 x86/x64

Description:
------------
1. use Test script to generate crash.php, size 8192 bytes
2. now let crash php engine crash.php
3. Any php file of size 8192 bytes crashes Apache and PHP!
4. Tested with Apache 2.2.21 V9 apache longue, PHP 5.4.0 RC5 or RC6 dev on 
three other machines, Win 7 x86 or Win 7 x64.

Test script:
---------------
testcase php file generator:

<?php

 $out='<?php//';
 for($z=0;$z<8192-9;$z++){$out.=mt_rand(0,9);}
 $out.='?>';

 file_put_contents('crash.php',$out);

 print('1. testcase file generated: crash.php, size '.strlen($out).' 
bytes<br/>');
 print('2. now let crash php engine <a href="crash.php">crash.php</a><br/>');
 print('<b style="color:red">3. Any php file of size 8192 bytes crashes Apache 
and PHP!</b><br/>');
 print('4. Tested with Apache 2.2.21 V9 apache longue, PHP 5.4.0 RC5 or RC6 dev 
on three other machines, Win 7 x86 or Win 7 x64.<br/>');
?>
