Hello Jørgen,
We have found that GCC 5 has a bug related to optimizations which may
cause DHCP DDNS module to fail. Please see:
- http://kea.isc.org/wiki/KeaKnownIssues
- http://kea.isc.org/ticket/4243
- http://kea.isc.org/ticket/4242
and the GCC and BOOST bugs we have opened for it:
- https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69789
- https://svn.boost.org/trac/boost/ticket/11989
May I suggest that you recompile Kea without code optimizations and see
how that works for you?
./configure ....... CXXFLAGS="-g -O0"
