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.
