Description:
------------
ext/xmlrpc/tests/bug42189.phpt fails consistently on 64 bits architectures such as ia64 and x86_64.

I modified the test a bit to show what's going on. From a quick look at the code it appears to be a bug in the XMLRPC-EPI lib and not in the module itself.


Test script:
---------------
<?php
$a = '~~~~~~~~~~~~~~~~~~';
$ok = xmlrpc_set_type($a, 'datetime');
var_dump($ok);

if ($ok)
    echo xmlrpc_encode($a);

echo "Done\n";
?>

Expected result:
----------------
bool(false)
Done


Actual result:
--------------
bool(true)
<?xml version="1.0" encoding="utf-8"?>
<params>
<param>
 <value>
  <dateTime.iso8601>~~~~~~~~~~~~~~~~~~</dateTime.iso8601>
 </value>
</param>
</params>
Done
