You guessed it! The symptom on linux was that the actual text for the classtype (indexed by classtype from the classification file) was missing and in its place was the string " sid". I'm fairly certain that another user thought that the classtype text in the classification file was too long and causing a core dump, was the result of the multiple classtype options for that one rule. That rule does not have to trigger, just one of the rules in the class "classtype". I'd be interested if the MAC actually works, or their is some other innocuous symptom similar to missing classification text.

It is possible that snort will core dump (depends on the OS) if this rule exists (doesn't have to trigger). rules/web-cgi.rules: alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS $HTTP_PORTS (msg:"WEB-CGI bash access";flags:A+; uricontent:"/bash"; nocase; reference:cve,CAN-1999-0509; reference:url,www.cert.org/advisories/CA-1996-11.html; classtype:web-application-activity; classtype:web-application-activity; sid:885; rev:5;) I'll leave it to the reader to figure out what is wrong with the rule.
