--- Comment #10 from James Michael DuPont <JamesMikeDuPont at googlemail dot com> --- I have reported the problem in the code to boost, they have fixed it. https://svn.boost.org/trac/boost/ticket/8651#comment:1 The problem is having to do with underspecifed namespace selection. They changed the code to remove the crash. mike
