Bug description:  "case" causes AV

This script let php crash.
The Problem is the case-statement in the convert_field_crash-function, but
with an If-statement this crash doesen't occur.

<?php

define('adDBTimeStamp', 135);

$conn = new COM( "ADODB.Connection" );

$rs = new COM( "ADODB.Recordset" );
$conn->Provider = 'SQLOLEDB';
$conn->Open( "Server=wincubix;Uid=oebb;Pwd=oebb;Database=cubix" );
@$rs->Open( "SELECT * FROM news ", $conn);

echo '<table>';
while (!$rs->EOF) {
	echo '<tr>';
    for ($i=0; $i < $rs->Fields->Count(); $i++) {
   		echo '<td>';
		echo convert_field_crash($rs->Fields[$i]);
   		echo '</td>';
    }
	echo '</tr>';
    $rs->MoveNext();
}
echo '</table>';

$rs->Close;
$conn->Close;

$rs->Release();
$rs = null;

$conn->Release();
$conn = null;

function convert_field($field) {
	if ($field->type == adDBTimeStamp) {
		if (empty($field->Value)) return '';
		return strftime('%Y-%m-%d %T', $field->value);
	} else {
		return $field->Value;
	}
}

function convert_field_crash($field) {
	// case verursacht AV
	switch($field->type) {
		case adDBTimeStamp:
			return strftime('%Y-%m-%d %T', $field->value);
			break;
		default:
			return $field->Value;
	}
}

?>
