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.
...
It fails even on simple file like this:
# cat /tmp/test.log
1.2.3.4
Are somebody using dns-terror on FreeBSD 10.x? What can I do to debug
and solve this problem?

I am still not able to solve this problem. Dns-terror is failing on all our
machines with FreeBSD 10.2.
1) Is somebody using it on 10.2 without problems?
2) How can I build it with some kind of debugging? (I am not C programmer, I
don't know this stuff)

Hm, fastresolve depends on dns/adns, what happens if you run the following
command? (to test if it not an issue with libadns)
$ /usr/local/bin/adnslogres $logfile
I tried this before and adnslogres works without any issue. The problem
(Bus error / core dump) is only with dns-terror command and only if it
find some IP address in the log. core dump when trying to resolve this
IP. If log doesn't contain any valid IP dns-terror doesn't crash.
It is the same on all 10.2 machines. All machines have fastresolv
package from the same poudriere build.
Machine with 8.4 i386 works fine (fastresolv is also build in poudriere)
I don't know how can I debug it with truss / ktrace / gdb.
