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

[Daniel-Constantin Mierla]

Hello,

did the message was received via network from kamailio and attempted to 
be parsed or you gave it directly to the function for parsing? If the 
second case, then be sure the buffer is null-terminated.

Cheers,
Daniel
