I still do not understand. What would be a purpuse of such tool?
Intended usage of BOOST_CHECLPOINT is like this:

void test_case() {
... some code
BOOST_CHECKPOINT( "Some test 1" );
... some code
BOOST_CHECKPOINT( "Some test 2" );
... some code
}

Now if any kind of runtime exceptions/signals occures (like SIGFPE) 
you may try to locate where it happends.

Regatds,
