Hi, I have a problem with a hash-index to a member of type std::vector<std::strings>. With boost 1.34 it compiles and runs find, but it fails to compile with 1.33! Unfortunately I do not have the luxury to change boost-version. Is there any way around this? I defined my multi_index_container like this: typedef std::vector<std::string> keys_type; struct entry_type { keys_type keys; bool operator<(const entry_type& e) const { ... } }; typedef boost::multi_index::multi_index_container< entry_type, mi::indexed_by< mi::hashed_unique< mi::tag<hash_index_tag>, mi::member<entry_type, keys_type, &entry_type::keys> >, mi::ordered_non_unique< mi::tag<pred_index_tag>, mi::identity<entry_type> >

mi_entries_type;

And get the following compile-error (see the bottom): /usr/bin/g++ -m64 -pipe -Wall -fPIC -O3 -DNDEBUG -I../framework -I/sitestat/src/nightly/2007-06-14/branches/rel-6-00/src/build/../../src/cgi
