New Comment:
There is no memory leak, those leaks are reported at script shutdown by
the Zend Engine.
to fix your problem do this
preg_match("/bar/", (string)$xml->name);
yes, cast it to string.

little imprecision fix: Memory is only increasing until hitting
configured memory if you replace the limited for-loop by a while(true)

Description:
------------
If you use a SimpleXMLElement as parameter for preg_match or
preg_match_all, memory is lost.
P.S.: If you cast the parameter explicit with (string)$xml->name memory
usage doesn't increase. So i suppose it's an problem related to internal
casting.
Reproduce code:
---------------
<?php
$xml = simplexml_load_string("<root><name>foo</name></root>");
for ($i=1; $i<=20; $i++) {
preg_match("/bar/", $xml->name);
// or preg_match_all("/bar/", $xml->name, $matches);
echo "Memory usage after $i iterations: " . memory_get_usage() .
"\n";
}
?>
Expected result:
----------------
I would expect an more or less equal memory usage.
Actual result:
--------------
Memory usage is constantly increasing until hitting configured memory
limit
