New Comment:
Sorry - I don't understand. Your example repeatedly appends to a
string, which of course will legitimately increase the size of the
string until it eventually fills memory.
I don't understand how this is the same as repeatedly allocating an
object. My example doesn't maintain a reference to the object, so
surely it should be garbage collected immediately?
In fact, if I replace SoapClient with an object of my own making then
memory usage remains constant:
<?php
class Foo {
private $bar;
public function __construct() { $bar = "Hi there!"; }
}
while(true) {
new Foo();
}
?>
What am I missing?
Thanks!

Ah, I should get glasses. You can also get all memory used with
something like this:
while (1) { $foo.= "bar"; }
Not bug but expected behaviour. Just don't do that!

Same result (on Windows - haven't tried it on Linux yet)

Description:
------------
SoapClient doesn't seem to clean up after itself when garbage
collected. It leaks something around 4K each time. Tested on both
Windows and Linux.
Reproduce code:
---------------
<?php
while(true) {
new SoapClient("test.wsdl");
}
?>
Expected result:
----------------
Assuming that I understand the PHP Garbage Collector (and it's possible
that I don't - I'm struggling to find any good documentation on exactly
how I should expect it to behave - any pointers very welcome!), I would
expect the memory usage of this script to be constant.
Actual result:
--------------
The memory usage increases very quickly (growing to several hundred
megabytes in less than a minute).
