Hi; i make a new dissecotr but when i use it a message
arror appear in COL_INFO and in tree window. The error
is: Dissector Bug Protocol LLCSTLB:proto.c:1187 failed
assertion "(guint)hfindex <gpa.info.len"]
LLCTLB is my dissector; here is the code od
packet-LLCTLB.c it puts COL_INFO and PROCOL_INFO well.
