Description

Parsing bug: Given 2 or more outputs for one capture in the regex, there will be a segmentation fault.

For example,

alert tcp any any -> any any (msg:"get username in nntp"; \

content:"USER"; \
pcre: "/AUTHINFO USER\r\n/i, pkt:nntp_username, pkt:nntp_password";\
sid:2000020;\
gid:100;)
