i noticed there was a 3-month old, low priority ticket for the if Odd failing. i came up with what is probably a dirty hack, but basically i changed:

line 647 in VariableData.php from

function Odd() {
	return !$this->iteratorPos % 2;
}

to

function Odd() {
	return !$this->Even();
}

it seems to work, and so far hasn't caused any weird spikes in performance. hope this helps those of you in need of a quick fix, until someone who knows PHP can fix it properly.

That fix looks good; can you post it to open.silverstripe.com so that we can integrate it with the core? :-)

i just uploaded to open.silverstripe.com - i added the file to the original trouble ticket. not sure if that's the right way to do it.
