Does not seems very convinient cause you need to change the code every time
While would you have a statement like
BOOST_CHECK_IS_SAME it would print to you "value" n case of failure

The problems with buggy compilers may question this statement.

No it does not. It very simple to setup MS IDE (is it what you are talking
about?) so that you will jump with F4 through the list of runtime errors.
