There have been no other reports of problems, but that doesn't mean too 
much. If you can stand risking another crash, a core dump would be 
really useful to chase this down.

Quick instructions for getting that, please ask if you need more detail:

1) build from source with debugging symbols

apt-get source dnsmasq
cd dnsmasq-2.16
make CFLAGS=-g

2) allow core dumps
ulimit -c unlimited

3) stop existing dnsmasq process
/etc/init.d/dnsmasq stop

4) run in debug mode
src/dnsmasq -d

If it goes pop, send src/dnsmasq and the corefile to simon@thekelleys.org.uk
