Hi list, I am encountering a problem with MultiIndex which can be resolved by disabling SAFE_MODE. As I actually do not get the problem in the code attached below I'd like to ask for an explanation. The marked line of code (i.e. the second iterator assignment) seems to be responsible for blocking MultiIndex's dtor in safe_mode.hpp: void detach_all_iterators() { for(safe_iterator_base* it=header.next;it;it=it->next)it->cont=0; } Why is this and how can it correctly be avoided? Cheers, Martin (boost 1.33.1, gcc 3.4.5) #define BOOST_MULTI_INDEX_ENABLE_INVARIANT_CHECKING #define BOOST_MULTI_INDEX_ENABLE_SAFE_MODE #include <boost/multi_index_container.hpp> #include <boost/multi_index/member.hpp> #include <boost/multi_index/ordered_index.hpp> using boost::multi_index_container; using namespace boost::multi_index; struct T1{}; struct T2{}; typedef int T; typedef std::pair<T,T> value_type; typedef multi_index_container< value_type, indexed_by< ordered_unique< tag<T1>, member<value_type,T,&value_type::first> >, ordered_unique< tag<T2>, member<value_type,T,&value_type::second> >
miT;
int main(){ miT::const_iterator it; miT map; it = map.get<T1>().end(); map.clear(); it = map.get<T1>().end(); // *** this hangs dtor! return 0; } __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
