yes, that's a reproducible bug, thank you.

The embarassing thing is that we've fixed this bug already for approxfun() -- and some of us know that spline* and approx* have originally been very much in parallel...

BTW: No need to give the function a name: S can nicely work with

     anonymous functions. Consequently, you can get the same effect from

    splinefun(vector(length=0), vector(length=0)) (1)

or, even a bit more compactly:

    splinefun(1[0], 1[0]) (1)
