Hi John,
In mss main.c -> Line 407, I added NULL that was cleared my error..
Now I am in a next issue which I couldn't able to run my parserTLV.py..
Am attaching the parser code which is taken from forum:
#!/usr/bin/python
# -*- coding: utf-8 -*-
import struct
import sys
import math
#
# TODO 1: Find the first occurrence of magic and start from there
# TODO 2: Warn if we cannot parse a specific section and try to recover
# TODO 3: Remove error at end of file if we have only fragment of TLV
