I'll investigate it and let you know what I find. The big change between 4.22SOC5 and 4.22SOC6 was the massping migration, which changes the way host discovery is done. That shouldn't affect port scans, but you never know.
I was also able to reproduce this bug. It crashes during connect scan, in scan_engine.cc:3050 in static bool do_one_select_round(UltraScanInfo *USI, struct timeval *stime) [...] for(hostI = USI->incompleteHosts.begin(); hostI != USI->completedHosts.end() && numGoodSD < selectres; hostI++) { [...] It seems that one of the lists is corrupted (I bet USI->incompleteHosts). I also think that the bug was introduced with 4.22SOC6. (and there were changes to do_one_select_round between SOC5 and SOC6) MM. _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
