Several crashes in 3.0.1

[David Petera]

Hello Yureka,

you are right that this should not be happening.

Would it be possible for you to enable core dumps on the routers and try 
to get core files of the aborts?
If core files and binary are not easy to obtain, simple backtraces will 
help us too.

We also need your config file.

Thank you for testing BIRD v3!
David
