I guess that OSPF iface option 'rx buffer large' should also fix this.   Could you try it? But definitely, it shouldn't crash even without this.

Thank you. Of course it's helps. The only thing i could do is http://bit.ly/1alMqek Just one question: do i need to add this option on interfaces to core? Now i have no problem with them.

  Could you get core dump of crashed BIRD for me? (i.e. run BIRD with   ulimit -c unlimited get it crashed.)
