Hi,
I am using dns-terror to resolve IP addresses in Apache logs for many
years on FreeBSD but it doesn't work on newly upgraded machines. It
works fine on 8.4 but core dump on 10.1 and 10.2 amd64.
Tested on 5 machines. Port is compiled on 10.1 or 10.2.
+pid 62102 (dns-terror), uid 0: exited on signal 10 (core dumped)
+pid 62105 (dns-terror), uid 0: exited on signal 10 (core dumped)
+pid 62111 (dns-terror), uid 0: exited on signal 10 (core dumped)
+pid 62114 (dns-terror), uid 0: exited on signal 10 (core dumped)
+pid 62117 (dns-terror), uid 0: exited on signal 10 (core dumped)
+pid 62123 (dns-terror), uid 0: exited on signal 10 (core dumped)
Tested command is simple
dns-terror -p 1000 -d /var/tmp/ip2host.db -o < /var/log/httpd/access.log
I tried to change 1000 tu another number and also tried empty ip2host.db
without any difference.
I get this with verbose output
# dns-terror -vvv -p 100 -d /var/tmp/ip2host.db -o <
/var/log/httpd/access.log

It fails even on simple file like this:

1.2.3.4
Are somebody using dns-terror on FreeBSD 10.x? What can I do to debug
and solve this problem?
