Please apply the following patch. It should help. Note that the tests will still not pass.
They were originally written for InterBase 4 and PHP 3 and must be fixed to
reflect the changes in InterBase 6 and some in the PHP 4's InterBase API too.

No feedback, but as this is the same problem as in #7117 that was confirmed to
be fixed by reporter, closing.
