Forgot to add, that I send only single one query to resolver:

$ host 
w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.w.pl
 127.0.0.1

Resolver properly returned response with A record,
but host utility timeouts for some reason (it probably sends MX query 
subsequntyl).

From valgrind report it looks that problem is in domain name / label 
compression code.

By they way, in past there was very similar problem was CVE-2002-2097, which 
also
was a bug in compression code in maradns.
