[boost] BOOST_CHECK_EQUAL broken/changed?

This one really bit me badly: BOOST_CHECK_EQUAL now evaluates it's arguments *more than once*, for example I have many tests that look like: BOOST_CHECK_EQUAL(*it++, 0xD800u); But the expression *it++ gets evaluated multiple times, and that really screws up the tests :-/ IMO I can't see any good reason for such a change?
