This clearly a dnsmasq bug: it shouldn't segfault, but the description
relies of lots of other "stuff" which makes it difficult to work out
what systemd is doing to provoke the problem. It there a way to find
out how systemd is invoking dnsmasq (ie the command-line) and how it
differs between the systemd-resolved stopped and systemd-resolvd started?


Cheers,

Simon.
