[sr-dev] kamailio parse_msg() API crashes when anonymous packet is passed to it

[varun pratapsingh]

HI All,

According to Kamailio Devel Guide it is mentioned that pasrse_msg()
fucntion returns 0 if it it parses the sip message finely and >0 if error
occurs.

I pass a anonymous packet to this function (packet which is not sip packet)
then it should return >0 value but the function crashes.

Here is gdb back trace:
