The code is (obviously) ill-formed and it does not compile, but it is 
not the point.  I get the following message:
> /usr/include/boost/mpl/aux_/preprocessed/gcc/apply.hpp:48:1:   [ 
> skipping 4 instantiation contexts ]
Can I get a full traceback?  I am interested in what happens in the guts 
(in particular, operator *).  Of course, I could try to reproduce the 
context of the caller explicitly but that is rather troublesome.  In 
this particular case, it requires the following code:
> typedef
> ::boost:: fusion:: result_of:: begin
> <  
> ::boost:: fusion:: transform_view<  ::std:: pair<  int, int>  const, int>  >::
> type
> const&offending_iterator_20;
> template
> void ::boost:: fusion:: detail:: print_sequence_loop:: call
> (::std:: ostream&, offending_iterator_20, offending_iterator_20,
>   boost:: mpl:: false_);
