New Comment:
But if it's just a general PHP design problem, why does
ereg("/bar/", $xml->name);
behaves different than
preg_match("/bar/", $xml->name);
regarding memory-usage?

PHP was never designed for 'long time run'. If you do it, you're
totally on your own. And this win32service is PECL thing so any bugs
with it should be reported at http://pecl.php.net/bugs/

Same effect with PHP 6.0.0-dev (php6.0-200708021030.tar.bz2)

Hello Judas!
In my case it's an long-term running script (using php-cli). So script
shutdown doesn't occur timely. Casting to string looks for me like junst
an workaround because
1) other functions like ereg doesn't have the same problem. Try it
with
ereg("/bar/", $xml->name);
instead of
preg_match("/bar/", $xml->name);
2) if the engine expects an string and therefore cast the value
internally, why should this behave different than casting manually in
sight of memory usage?
Best regards
Daniel Chabrol

I can vouch for the workaround based on a similar issue (see
http://bugs.php.net/bug.php?id=41911) I encountered. Unfortunately that
bug got marked as bogus with a similar explaination.
I accept that in 99% of uses of PHP where script shutdown occurs that
this type of memory leak is acceptable. However, in my case I am using
PHP persistently with the win32service module (php.net/win32service). In
the end I have had to setup a routine to restart the service every few
minutes to workaround this type of memory leak instead of trying to
track them all down.

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.
