Hi again Volodya, after thinking this over I'm not so sure the mpl::deref thing has anything to do with your problem --still, it'd be good to know whether it has some impact, if you can do the test locally.
As I've mentioned in the other email, the change did not fix the problem.
I'm afraid we're in Alexsey's hands to solve this out.
Seems so.
BTW, boost/bind/arg.hpp is deceivingly simple I can't figure out how its inclusion can make a difference.
Well, I can tell one third of the story. The reverse_iter_fold.hpp has this:
namespace boost { namespace mpl {
template< typename BOOST_MPL_AUX_NA_PARAM(Sequence) , typename BOOST_MPL_AUX_NA_PARAM(State) , typename BOOST_MPL_AUX_NA_PARAM(BackwardOp) , typename ForwardOp = arg<1>
According to the error message, gcc associates 'arg<1>' with boost::arg (from bind/arg.hpp), while most likely mpl::arg<1> was meant. Two remaining questions are - why gcc does that.
GCC applies "ADL" to almost everything. It's ridiculous.
- why changing the above to mpl::arg<1> does not fix anything?
That part I can't fathom. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
