sorry .. quick note - the server this runs on has
register_globals on .. (I know, we're working on it:p)

I've managed to track the leak down to the following section
of code .. just load this into a page and refresh it a few
times to see the leak. It also will not work if it in the
root of the virtual host - eg: /leak.php it will not leak, /
leak/leak.php and it will ..
$gb_loggedin = false;
if (isset($storeuser_id)){
//cookie is available
if ($storeuser_id != "") {
$gb_loggedin = true;
//reset cookie just to make sure.
setcookie ("storeuser_id", $storeuser_id,time()
+31536000);
}
}
Let me know if this helps.

No, the files listed do not help to track it down.
You can try to compile PHP with --disable-zend-memory-manager and see
if valgrind can add some more info, but I suspect that there are no
valgrind for your platform.
Try to reproduce it on an Intel-based server and see if you can get
more info with valgrind.
But still a short reproduce code would be even more appreciated.

Ok .. I've spent a couple of hours summarising the page to
see if I can supply code for you here and havent had much
luck.
Any idea what I should be looking for in the code ?
Do the files listed help track down what I should be looking
for ?
/php-5.1.2/ext/standard/string.c(3006)
/php-5.1.2/Zend/zend_alloc.c(237)
/php-5.1.2/main/php_variables.c(186)
Thanks
