Hello,

I use Dibbler client 0.8.2 on Linux with the following configuration:

log-mode full
log-level 8
downlink-prefix-ifaces eth0
iface "ppp0" {
  pd
}

The reason is to get the IPv6 prefix via my ADSL line (ppp0 is PPPoE),
which is announced by radvd to my LAN (eth0). I have to use PD to get
the IPv6 prefix routed to me by my ISP.

Sometimes Dibbler client crashes with these last lines in its log:

2012.06.11 06:08:55 Client Info      Generating RENEW for 0 IA(s) and 1 PD(s).
2012.06.11 06:08:55 Client Error     Unable to find interface with ifindex=39
2012.06.11 06:08:55 Client Debug     Authentication is disabled, not
including auth options in message.

and the kernel log says this:

kernel: dibbler-client[13365]: segfault at 4 ip 006b4376 sp bff34cbc
error 4 in libc-2.12.so[636000+189000]

Is there anything I can do to prevent this crash? Obviously I can
detect these error messages and restart Dibbler client, but this is
not the solution I am looking for.
