Re: [Boost-users] [proto] Object got sliced when passed by reference

I just compiled your smaple using g++-4.5 and i got: logical_and( logical_or( terminal(4baseI2F1E) , terminal(4baseI2F2E) ) , terminal(4baseI2F3E) ) hodqhoqw 0 Why is I think the correct answer. So this is tied to some MSVC specific behavior, i guess mayeb on how the terminal< base<_> const &> is matched. matching terminal< base<_> > should be enough I think no ? Could you try ? HTH
