segfault with exabgp and bird 1.4.2

[Charlie Allom]

Hi,

I have been running a stable mesh with a BIRD peer in a mesh for a few
weeks now.

Trying to connect with ExaBGP makes BIRD segfault. How can I debug this further?

Here is the TCP stream: https://spodder.com/~yeled/bird.pcap

It seems innocuous to me.

  C.

~% ulimit -c 100000

~% file ./bird
./bird: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for
GNU/Linux 2.6.8, dynamically linked (uses shared libs), not stripped

~% sudo ./bird
bird: Hello or poll interval less that 5 makes cryptographic
authenication prone to replay attacks

~% sudo ./birdc
BIRD 1.4.2 ready.
Connection closed by server.
