Description:
------------
Calling Oracle stored procedure cause the apache http daemon segmentation fault on FreeBSD6-STABLE box.

Used software:
ZendOptimizer-2.6.0
apache-2.2.0_4
oracle8-client-0.1.1_1
pecl-PDO-1.0.2
pecl-PDO_OCI-1.0
php5-5.1.1


Reproduce code:
---------------
<?php
    $dbh = new PDO("oci:dbname=dbhost", 'user, 'pass');
    $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "CALL sp_test('p1','p2','p3',?,?)";
    $stmt = $dbh->prepare($sql);

    $out_param1 = "a";
    $out_param2 = "a";

    $stmt->bindParam(1,$out_param1,PDO::PARAM_STR, 1024);
    $stmt->bindParam(2,$out_param2,PDO::PARAM_STR, 1024);

    $stmt->execute() // <===== !!! this is line 14
        or die ("<pre>Execution error:\n" . print_r($dbh->errorInfo(), true));

    $dbh = null;

    print $out_param1 . " ". $out_param2;
?>


Expected result:
----------------
This code should print in a browser window two strings returned from SP. In my case - "Stored" and "procedure"

Actual result:
--------------
I'm failed to produce backtrace because gbd coredumps:
# ulimit -c unlimited
