I agree that the insn is invalid. It probably should be something like this:

 (parallel [
             (set (reg:PSI 7 fb)
                 (mem:PSI (reg:PSI 7 fb) [0 S4 A8]))
             (set (reg:PSI 8 sp)
                 (plus:PSI (reg:PSI 7 fb)
                     (const_int 2 [0x2])))
             (return)
         ])

I.e. one set of sp and fb each. The faulty pattern is named "epilogue_exitd".
The two patterns "prologue_enter_16" and "prologue_enter_24" are also broken in
that they use 
(parallel [
    ... (pre_dec (SP_REGNO))
    (set (SP_REGNO) ...)
])
which is just another invalid use of PARALLEL. DJ?

On the AVR, my bets are on the define_insn "call_prologue_saves" with two sets
of (reg:HI SP_REG) inside the implicit parallel.
