Hi All! This program demostrate the problem <code> #include <boost/multi_container_index.hpp> #include <boost/multi_index/ordered_index.hpp>

int main(int argc, char* argv[] typedef boost::multi_index::multi_index_container<int> int_set; int_set s; int_set::iterator itr = s.begin(); ++itr; return 0; }

</code>

Program hangs up in increment if s is empty. I undestand that this is my problem. But may be "assert" can be inserted for such cases

Hi Ilya You can enable the so-called safe mode by inserting this #define BOOST_MULTI_INDEX_ENABLE_SAFE_MODE prior to the inclusion of Boost.MultiIndex headers. With this mode switched on, this problem (and many others) gets asserted. More info about safe mode in http://boost-consulting.com/boost/libs/multi_index/doc/advanced_topics.html#...
