[Boost-users] [Foreach] Trouble iterating over Boost.MultiIndex containers

I'm having trouble using BOOST_FOREACH to iterate over Boost.MultiIndex 
containers. I've attached a testcase, which fails to compile because of what 
looks like an ADL collision between range_iterator's end() and boost::mpl::end.

I'm using GCC 3.4.2 with foreach.hpp revision 1.22 from the sandbox. Others have 
reported that GCC 4.0.0 20050130 is also affected.

(I'm aware that BOOST_FOREACH isn't part of Boost yet, but it's in the review 
queue so I thought posting this here was appropriate.)

Regards,

Eelis


#include <boost/multi_index/sequenced_index.hpp>
#include <boost/multi_index_container.hpp>
#include <boost/foreach.hpp>

namespace mi = boost::multi_index;

typedef boost::multi_index_container<int, mi::indexed_by<mi::sequenced<> > > C;

void f (C const & c)
{
  for (C::const_iterator i = c.begin(); i != c.end(); ++i) { int r = *i; } // ok

  BOOST_FOREACH(int r, c) {} // errors
}
