The debug implementation is not thread-safe, even if different threads are using separate iterators for reading elements of the container. BOOST_CB_DISABLE_DEBUG macro is no longer used, BOOST_CB_ENABLE_DEBUG=1 should be defined instead to enable debug support. Fixes https://svn.boost.org/trac/boost/ticket/6277.
