Huh? I _never_ build it as dynamic extension.

Yes, I think you are right. It is probably some clash between the
specific versions of Apache/mod_ssl, OpenSSL, PHP/OCI modules and
Instantclient.
Even though I don't understand, why this clash isn't reported during
the linking or the loading of the libraries.
I have tried with the newest instantclient and there is no change.
Just to summarize, I have:
Ubuntu Linux 6.06
Apache 1.3.34 with mod_ssl 2.8.25
OpenSSL 0.9.8a
PHP 5.3.2 with oci8.so a pdo_oci.so as dynamic modules at the same
time
Instantclient 10.1.0.5.
Last notice: If pdo_oci is compiled statically into PHP and oci8
dynamically (it refuses to be built static), it works fine. I think I
can accept this as a workaround.
And if there is someone else unfortunate enough to meet the same
circumstances as me, i hope this helps him at least a little bit ;-)

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.
