Description:
------------
I compile Apache+PHP with using Instantclient. For that are done the changes in Makefile:
--with-oci8=instantclient,/opt/instantclient

Then I have to change the file /opt/apache2/bin/envvars. I
add the following lines:
unset ORACLE_BASE ORACLE_HOME ORA_NLS ORA_NLS33 ORACLE_SID LD_LIBRARY_PATH
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
export LD_LIBRARY_PATH=/opt/instantclient:$LD_LIBRARY_PATH 

But after starting Apache crashs.
If I delete ORACLE_HOME from the file, Apache works but PHP does not.

More details:
OS: SuSE Linux 9
uname -a:
Linux oracle 2.6.5-7.257-bigsmp #1 SMP Mon May 15 14:14:14 UTC 2006 i686 i686 i386 GNU/Linux
Apache 2.2.3
Oracle 10.2.0.1.0
PHP 5.1.2

I have compiled the latest version but it didn't help. There is the same error when the line "unset ORACLE_HOME"  is put in the file envvars.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Here is a backtrace:

Also i can note that there are Oracle base and Instant Client on the server. Their version is 10.2.0.1.0
The line 'unset ORACLE_HOME' is necessary in the file /opt/apache2/bin/envvars in order to use libraries of Instant Client but not Oracle base.

Also, i can provide an account for you in order to reproduce/investigate this problem on our server.

[2006-11-13 11:29 UTC] tony2001@php.net

Thanks, no need for an account, the backtrace clearly shows that the problem is not in PHP, but in libnss.

Thank you for your help. I'll try to resolve the issue by installation of a later version of the library.
