Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows (zip):
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

For Windows (installer):

  http://snaps.php.net/win32/php5.2-win32-installer-latest.msi

I've tried both PHP 5.2 and 5.3 and cannot reproduce the crash.

Description:
------------
Long names cause segmentation fault in 'instanceof' and 'new'
operators.

Reproduce code:
---------------
<?php

$a = str_repeat("a", 10000000);

# call_user_func($a); // Warning
# $a->$a();           // Fatal error

if ($a instanceof $a); // Segmentation fault
new $a;                // Segmentation fault


Expected result:
----------------
Warning / Fatal error

Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
