I'm not sure what you're asking (since get_matching_terms() uses
MSetIterator internally!)

But I just reread the original thread.  To summarise, this has the odd
bug under MSVC:

    $terms = join(" ", $enq->get_matching_terms($mset->get_hit(0)))

But this works:

    $hit=$mset->get_hit(0);
    $it=$enq->get_matching_terms_begin($hit);
    while (! $it->equals($enq->get_matching_terms_end($hit)))
    {
	echo $it->get_term(), ' ';
	$it->next();
    }

I thought someone had said that this worked, but I can't find where
anyone did, so perhaps I misread one of the mails before:

    @terms = $enq->get_matching_terms($mset->get_hit(0));

If that doesn't work either, this is more serious (but perhaps more
likely to be possible to track down).

It would be interesting to check that, and to try gradually changing the
code and see if/when the problem goes away.  That might offer some
insight into what's going on.  I can't test it myself, but I could talk
someone through it on IRC or IM if they need a hand.

Cheers,
