Public bug reported:

Binary package hint: php5-interbase

Description:    Ubuntu 8.04
Release:        8.04

php5-interbase:
  Geïnstalleerd: 5.2.5-0ubuntu1
  Kandidaat: 5.2.5-0ubuntu1
  Versietabel:
 *** 5.2.5-0ubuntu1 0
        500 http://nl.archive.ubuntu.com hardy/universe Packages
        100 /var/lib/dpkg/status


Running the following script in php5 (in cli or from apache2) with 
php5-interbase extension loaded, consistently triggers a segfault.

<?php
$host = '/path/to/your/database.fdb';
$user = 'sysdba';
$pass = 'masterkey';

$dbh = ibase_connect($host, $user, $pass);
$sql = 'SELECT * FROM SOMETABLE WHERE SOMEKEY = ?';  // only one parameter
$sth = ibase_query($dbh, $sql, $user, $pass);   // too many parameters given
while ($row = ibase_fetch_assoc($sth)) {
        print $row;
}
ibase_free_result($sth);
ibase_close($dbh);
?>

Note that you need to adjust $host and $sql to meaningful values for
your environment.

I see the following error messages in /var/log/messages:
