I think you've just got a silly little goof there; your variable in the function
(sp@x) doesn't match the variable in the domain specification ({n,1,10}).
There is clearly a bug, though. I corresponded with Dan Lichtblau about
it off list. He confirmed the bug but said that is already fixed in the
development version.
