This looks like a symbol clash between OpenSSL and Oracle Client.
Try updating Oracle Client and searching their bug database.

Yes, these extensions are built together with the main PHP engine. I am
using libssl.so.0.9.8 that comes with Ubuntu 6.06. I think that Oracle
(instant-client) is not linked to openssl (at least not dynamically).
For details see below. Anyhow, with CLI the sames script works without
problems (both oci modules loaded).

Are each and every one of those extensions linked with same SSL
libraries? And none of them is linked with static ssl libs?

I have more details and the strack-trace (below). The problem appears
only if there are both oci8.so and pdo_oci.so loaded as dynamic modules.
If there is none of them loaded or just one of them present, it works
ok. When there are both of them, it segfaults. The static linking i have
not tried.

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.

Description:
------------
I have a PHP compiled with OpenSSL support. Calling function
file_get_contents with an URL should give me a string but it crashes
instead (segmentation fault).
If my PHP runs as CLI or Apache2 module, it works fine. If my PHP runs
as Apache1.3 module, it segfaults.
With HTTP url, it works. With HTTPS url it works for some sites and
crashes for others.
With PHP version 5.2.0, everything works fine under the same
circumstances (Apache1.3 module, HTTPS, same sites).
Reproduce code:
---------------
<?php
$s = file_get_contents( "https://www.mikropost.cz/index.php"; );
var_dump($s);
?>
Expected result:
----------------
The contents of the web-page.
Actual result:
--------------
Nothing - Apache process ends with segmentation fault.
