Description:
------------
In PHP 5.2.1 and PHP 5.2-200702180530, building and loading the pspell module causes php to crash on exit.


Despite the apparent location in the session module, commenting out the extension=pspell.so line in php.ini makes php exit without crashing.

Aspell is version 0.60.5.



Reproduce code:
---------------
To reproduce:

$ echo | php   
-ksh93: 59569: Memory fault(coredump)

$

Expected result:
----------------
$ echo | php             

$ 


Actual result:
--------------
