[Olsr-dev] OLSRd SegFault

[Ferry Huberts]

Please give me more info so that I can try to reproduce it.

How did you compile?
How did you run?
What do your interface look like (ifconfig)?

When does it crash? During startup?

It works fine for me.

Try to run with a debug version (DEBUG=1) and with -nofork.
If it crashes then repeat it using strace.
