[Oisf-users] suricata 2.0.1 segfault on nmap scan

[Rogier Mars]

Hi, 

I've been testing with suricata on a VM environment to test if I can use it in a production environment. While testing the IPS features I can repeatedly crash suricata with a core dump by running the following command: 

nmap -Pn -sS -A -f 192.168.100.35

Below the error message and the build-info. If you need more info please let me know and I will provide it. 

Kind regards, 

Rogier
