Filterlog core dump

[pLu]

2.3 RC:

pid 16031 (filterlog), uid 0: exited on signal 11 (core dumped)
pflog0: promiscuous mode disabled

I've seen it since at least 2.2.4 so it's about time to find that bug. Where can I find a debug build of filterlog (amd64)?

[cmb]

There is no debug version. It should be leaving a core file somewhere.

find / -name '*.core'

Your raw filter log contents may have a clue. You see anything in 'clog /var/log/filter.log' that correlates with the time of the crash?

[pLu]

The core file is conveniently placed in the root. I've also saved cores from 2.2.4 and 2.2.5.

filterlog was at some point restarted so any possible hints are long gone. There's only about four minutes of traffic in the log.

I need a binary that's built with -g and not stripped of symbols to get any useful hint.
