Quite weird indeed. And verified in all branches.

And it only happens with 'new'.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

simpleXML returns simpleXML objects when accessing properties of the 
document, and calling new on the returned object, creates a new object 
of that type returned.

You need to cast to string before calling new, i.e.:
$mclass = (string)$Xml->classname;
$XmlClass = new $mclass('<root />');
