Description:
------------
I believe we have a same/similar situation as PHP bug # 46473 (updated that bug report but got no response, so figuring I need to open a new report) running PHP 5.2.9 (and PHP 5.2.10) on 64-bit SLES10 - with the ibm-db2 1.8.2 pdo_odbc extension. Getting a "Child pid nnn exit signal Segmentation fault (11)". 
Program terminated with signal 11, Segmentation fault.
#0  _zval_ptr_dtor (zval_ptr=0x3fffff31c70)
    at /opt/SFI/php-5.2.9/Zend/zend_execute_API.c:412
412             (*zval_ptr)->refcount--;

Was able to circumvent by configuring (now, PHP 5.2.10) with
--enable-debug.  PHP 5.2.10 without --enable-debug fails the same way as did 5.2.9.  Can someone advise if this is the same problem  as bug# 46473 and a prognosis for correction?


Reproduce code:
---------------
Here is a simple recreate script trying to connect to the DB2 "SAMPLE" database:

<?php
 $dbconn = new PDO('odbc:SAMPLE','db2inst1','pw'); /* pw not actual pw
*/
?>


Expected result:
----------------
connection to DB.

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