Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.

Can anyone please, tell me how to overcome this error.
From the gdb output?
Because I can't recompile with new version of php at this time.
 [2007-02-27 14:07 UTC] tony2001@php.net 
Set ORACLE_HOME and other Oracle environment variables and make sure they are available to the Apache process.
 [2007-02-27 14:37 UTC] kmvijay at yahoo dot com

Below five are in PHP variables section
ORACLE_HOME 	/home/oracle/product/10.2.0/db
NLS_LANG 	AMERICAN

In this case, please update PHP first.

I have a previous, next button in my web page.
When I click previous button, it shows all the data, when contineously cliking previous button, then at some point the above error comes (partial data is displayed and Segmentation fault).
But when I use the gdb bt, I could'nt find the segmentation error?.

Previously I was using PHP 4.3.4, oracle9i, RHEL2.1. and apache 1.3.27 It works fine with oci8.

The same code I have ported to RHEL4, oracle10g, PHP4.3.9.,Apache 2.0.52, it gives segmentation fault.

Ok. I will update to latest version.
Can you please tell me which version is suitable for RHEL 4, Apache 2.0.52, Oracle 10g Release 2(10.2.0.1.0)?
