When running dhcpd and then pressing Ctrl+C it crashes and creates a core-dump.

Steps to Reproduce

1) Create a project with this configuration:

/wr/installs/lx8/wrlinux-8/wrlinux/configure --with-layer=meta-java,common,common-downloads --enable-board=qemuppc --enable-kernel=standard --enable-rootfs=glibc-small --enable-reconfig --enable-bootimage=cpio.gz.u-boot --enable-rm-oldimgs=yes --enable-internet-download=yes --with-template=feature/ntp428p10,feature/lttng --enable-checkout-all-layers=yes --with-package=dhcp-server --with-rcpl-version=0018

2) Build the image and run it into qemu with "make start-target"

3) Edit /etc/dhcpd.conf with this content (maybe you will need to edit the IP directions acording to your target, for qemu in my worstation this values worked fine):

ddns-update-style none;
deny bootp;
class "vendor-class-60"
match option vendor-class-identifier;
option domain-name "mycompany.local";
option domain-name-servers;
subnet netmask
option broadcast-address;
deny bootp;
default-lease-time 86400;
max-lease-time 604800;

option subnet-mask;
pool {
option routers;

4) Start dhcpd with these parameters: 

root@qemu0:~#  /usr/sbin/dhcpd -d -f -cf /etc/dhcpd.conf -lf /var/lib/dhcp/dhcpd .leases eth0

5) Press Ctrl+C, it will crash and will print this output:
