Bug description:different ways of iterating over an SplMaxHeap result in
different keys
Description:
------------
If I use a foreach-loop to iterate over an SplMaxHeap,
the first key is 1. If I use the "key" method, the
first key is 0.
Just in case it's relevant, this is the "configure"
command I used to compile PHP. (Don't be misled by
the value for "prefix"; I'm using PHP 5.3.13, not
PHP 5.3.12.)

Test script:
---------------
<?php
$heap = new SplMaxHeap;
$heap->insert(42);
foreach ($heap as $key => $value) {
break;
}
var_dump($key);
var_dump($value);
$heap = new SplMaxHeap;
$heap->insert(42);
var_dump($heap->key());
var_dump($heap->current());
Expected result:
----------------
I expect to see 4 lines of output from the script,
and, among other things, I expect the third line to be
the same as the first line.
Actual result:
--------------
The script gives this output:
int(1)
int(42)
int(0)
int(42)
Note that the third line differs from
the first.
