Bug#630733: Info received (Bug#630733: bind9: segfault when dnssec-lookaside auto enabled)

[Riku Valli]

It seems at bug is related to AMD Athlon(TM) XP 2500+ internal 
instruction set or something, because i got new computer with Intel(R) 
Core(TM)2 Duo CPU E6750 @ 2.66GHz and problem disappier. Dnssec work 
now. I only move existing configuration from old to new ones.


I have got similar problem with spotify and problem was at Athlon 
haven't sse2 instruction set.

 Howto reproduce add named.conf.options dnssec-lookaside auto; and restart 
 bind. Start also made core dump to /var/cache/bind directory
 Yes, this was working configuration and work again when comment 
 dnssec-lookside auto out.

Is the missing SOA message also printed with dnssec-lookside auto;
commented out?  Could this be caused by a corrupted journal file, or
might this be unrelated?
