At the very end of the executing any script produces segmentation fault. This only happens if compiled with oci8 support.

Have you specified the environment variables mentioned at
http://www.php.net/manual/ref.oci8.php

What is the oci8 version?

Yes. As I've metioned the script actually works. It only crashes when exiting. All the files get closed, changes are commited, etc.

Another thing that I've discovered last night is that this only happens if I compile oci8 support as a php shared module:
--with-oci8=shared,/ora01/app/oracle/product/8.1.6

It works fine if compiled with just:
  --with-oci8=/ora01/app/oracle/product/8.1.6

This is now only a minor problem. The bug report could probably be closed.
