Hi,
So I looked at this, and it wasn't great one way or the other...
The first patch here is obvious, let's just take it and get one
of the parsings out of the way.
The second one removes a couple of more cases where this is done,
since it only happens when the last argument is non-NULL.
The third then is to avoid the UAF, and is simpler now since only
a few places can even allocate it.

Sorry about the duplicate, I'm on a train to Berlin and network was
spotty.

No worries! I'll do a round of stable updates with what we have right
now tomorrow morning and then will look at these when I return home
later tomorrow evening. Thanks for doing them!
