c++ - Aborted: core dumped -


i have structure given below:

struct reply_t {         reply_t (unsigned int _xid){                xid = _xid;                cb_present = false;                buf = null;                sz = 0;         }         unsigned int xid;         bool cb_present; // whether reply buffer valid         char *buf;      // reply buffer         int sz;         // size of reply buffer };

i have std::map given below:

std::map<unsigned int, std::list<reply_t> > reply_window_;

now here problematic part:

std::map<unsigned int, std::list<reply_t> > :: iterator rep_window; std::list<reply_t> rep_list; std::list<reply_t> :: iterator rep_it; rep_window = reply_window_.find(clt_nonce);  if(rep_window!=reply_window_.end()){          for(rep_it=rep_window->second.begin(); \\                            rep_it!=rep_window->second.end();rep_it++){             if((*rep_it).xid<=xid_rep){                 (*rep_it).cb_present = false;                 free((*rep_it).buf);             }          } }

in above code trying free memory allocated *buf of struct reply_t pointed list iterator. not trying free memory allocated structure struct reply_t pointed list iterator. still when run code gives error below:

aborted (core dumped)

could please guide me going on in here?
