Hi, Really good find. Thanks for reporting this. We will investigate and fix the problem. Tom From: Snort-devel <snort-devel-bounces () lists snort org<mailto:snort-devel-bounces () lists snort org>> on behalf of Meridoff via Snort-devel <snort-devel () lists snort org<mailto:snort-devel () lists snort org>> Reply-To: Meridoff <oagvozd () gmail com<mailto:oagvozd () gmail com>> Date: Tuesday, November 20, 2018 at 11:03 AM To: "snort-devel () lists snort org<mailto:snort-devel () lists snort org>" <snort-devel () lists snort org<mailto:snort-devel () lists snort org>> Subject: [Snort-devel] Snort3: bug with "-z" when it only in config Hello, when option -z (total instances) is given only in config (snort["-z"]=true), then it equals to 1 (default ?) for some of inspectors/plugins/modules, because they inited between parse_cmd_line and parse_config (where -z lies). Due to this bug/feature for many instances we have access to uninted array p->pp_class.init[slot] in function InspectorManager::thread_init (), when slot > 1 but this array for some inspectors (appid ,telnet ,etc) has length 1 (see PHClass costructor). So we must duplicate "-z" in command line or do not use snort["-z"]=true at all.
