Ah, yes.  Silly me.  And print_debug doesn't need to be passed a
formatted string either.  Silly me again.

Perhaps though, there is a quick solution.
coroutine.running()  returns a thread.  The currently running thread in
fact - and you can print the thread id:

print( coroutine.running()  )

So what I'm thinking is that you could insert that statement right after:

stdnse.print_debug(5, "MSRPC: Entering unicode_to_string(pos = %d,
length = %d)", pos, length)

in msrpc.lua and then in the action() of each script that you're running do:

print( host.ip, coroutine.running()  )

which should tie a thread id to a host IP and allow you to cross
reference the thread id that failed.

Other than that, as you say, passing the host.ip and script id to the
library would work, but that would be a real pain in the arse as
best-practise for library use.
