No, it shouldn't. Dnsmasq should be collecting exit codes from its dead
children and does so fine in most circumstances.
If your script is just /bin/echo then quite possibly something strange
is going on with the child-process code.
Are you in a position to do some serious debugging on this (like maybe,
running dnsmasq under truss, to see waht syscalls it makes?)
