One other detail that might help in the investigation: I use hashed indexes in other places with custom key extractors as opposed to const_mem_fun and I get no warnings.

I think this problem is not actually related to Boost.MultiIndex, but
to Boost.Hash. Could you please try to compile the following

  // just including this
  #include <boost/functional/hash/hash.hpp>

both with Boost 1.33.1 and 1.34? Same behavior? Looking fwd
to your feedback.
