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. I'm afraid we're in Alexsey's hands to solve this out. BTW, boost/bind/arg.hpp is deceivingly simple I can't figure out how its inclusion can make a difference.

Vladimir, I don't have my compiler handy right now, but I think this is due to an overlook when doing the adaptation to the new MPL. In particular, the line 50 in boost/multi_index/detail/node_type.hpp:
typedef typename IndexSpecifierIterator::type index_specifier;
should be changed to
typedef typename mpl::deref<IndexSpecifierIterator>::type index_specifier;
(also, the corresponginf #include <boost/mp/defer.hpp> must be inserted) Could you please try this locally and report the results? If the problem is solved, I'll commit something along this line next Monday.
I don't know the rationale for having to use deref, since I thought these two expressions are equivalent, but there must be some difference, for Alexsey changed some of the code in multi_index to do that when mergien the new MPL.

The attached code, which use the multi_index library, produces screens of errors from mpl. The STLfilted log is attached too.
Commenting out #include <boost/bind/arg.hpp> makes the error go away, as well as including it after multi_index.
This happens with: gcc version 3.3.4 (Debian 1:3.3.4-6sarge1) gcc version 3.4.1 (Debian 3.4.1-4sarge1)
The code used to work some time ago, but I can't give the exact
date.>
I've tried too look at the problem, but got lost in MPL internals.
