[Dnsmasq-discuss] Badly formatted "dhcp-boot=" line crashes dnsmsaq 2.85

I inadvertently left a “tag:” off a “dhcp-boot=“ line which resulted in dnsmasq crashing.

This was the line that caused Dnsmasq to crash:


The line was supposed to be:


We are using 2.82 in production where the crash doesn’t happen until a matching packet arrives.

But I did also try 2.85 before submitting this report and it crashes whilst parsing the configuration file:

# /tmp/dnsmasq-2.85/src/dnsmasq -k -p0
Segmentation fault
