If dnsmasq re-reads a resolv file, and it's empty, it will retry after a delay. In the meantime, the old servers from the resolv file have been deleted, but the servers_array doesn't get updated, leading to dangling pointers and crashes. Thanks to Brad Jorsch for finding and analysing this bug. This problem was introduced in 2.86.
