Changes to a container while BOOST_FOREACH is iterating through it?

What would happen if a container that BOOST_FOREACH is iterating through is changed inside the BOOST_FOREACH scope?

Does BOOST_FOREACH "freeze" the initial state?

In this case behavior is undefined. Look at Hoisting and Iterator Invalidation in official documentation of BOOST_FOREACH.
