Hello!
I have tried to get the latest version of Knot running on my Raspberry Pi 2.
Unfortunately does Raspian only have packages for an old version. I updated
my Pi to debian jessie. There is actually a version of Raspian based on
jessie. That version of Raspian does come with slightly newer packages, but
still not up to date.
So I compiled my own version. 2.1.0-dev
Everything works fine until the moment I try to start knotd. IT will crash
with a segfault.
I did recompile with --enable-debug but I do not get any debug output in
syslog.
I did run with gdb and got the following information
SYSLOG:

It seems that the scanner thread is somehow missing. But why? Anybody with
experience with knot on armhf?
