Same issue as I get the exact same problem when using traceroute... :(

It's being caused by the reolver library. It looks like a NULL pointer being
referenced as a function, which would tend to imply that we have set hte
function pointer to NULL, and it only happens when select is involved. It
seems to be happenning in core so I'm guessing (and that's all it is at
present) that it's when we get a callback for a socket that we've closed.
I've added checks for this and it doesn't seem to be stopping it, so more
checks required I think!
