Description:
------------
Platform: 4-CPU machine, Apache 2.0.39..48, PHP 4.3.x, Win 2000 Adv.
server engl., OCI8, Oracle 8.1.7EE

When issuing multiple Oracle-requests at once, the Apache client thread
dies with protection fault (C0000005) without any further message from
PHP, Oracle or Apache.

Same code runs okay on one-CPU machine with same platform. Changing
Apache to 1.3.28 helped.

Could be a problem within the PHP for Apache2 parallelization on more
than one CPU.
