In the script file one calls during dhcp address operations, it is a
particularly bad idea to restart the server. Sending a HUP is fine, but
turning off the parent from the child is in a subshell is a Bad Idea (tm).
Replaced the call in my script from /etc/init.d/dnsmasq restart to
killall -HUP dnsmasq and it works without causing the segfault.
