Thanks for your reply.
Fortunately it seems that the segfault is a false alarm.
As it semt strange to me that Freeradius stop working by segfault, I
installed FR in another PC and I copy the same configuration.
Now it seems to be working, except that it stays in loop on DHCP
Discover (no Offer, no Request, no Ack).
