php module crash (maxdb-php-source-7_5_00_19.tgz)

Hi, 

Using this code:

<?php

$link = maxdb_connect("localhost", "DB", "user", "pass");

/* check connection */
if (maxdb_connect_errno()) {
    printf("Connect failed: %s\n", maxdb_connect_error());
    exit();
}

$query = "SELECT * from Authors";

if ($result = maxdb_query($link, $query)) {

    /* Get field information for column 'SurfaceArea' */
    $finfo = maxdb_fetch_field_direct($result, 0);

    printf("Name:     %s\n", $finfo->name);
    printf("max. Len: %d\n", $finfo->max_length);
    printf("Type:     %d\n", $finfo->type);

    maxdb_free_result($result);
}

/* close connection */
maxdb_close($link);



This code generates a Segmentation fault (using PHP 4.3.9). This ist the 
Backtrace:
Program received signal SIGSEGV, Segmentation fault.
