Hello,
could you, please, generate a core dump ? Use ulimit -c 1000000 to
enable core generation and reproduce the crash. Then compress the
compiled sources along with the core dump and send it to me.
thanks, Jan.

Hello!
During playing around with route headers I discovered that ser crashes
reproduceable when I send the following request to it with sipsak, I
think the invite is a valid request with strict routing.
