1. What is a short input program that triggers the error?

http://play.golang.org/p/m59dvc6cXo

Also a reduced example:

package main

type T struct {
    F int
}

func f() {
    var (
        A = [][1]int{}
        B = []int{3: 1, 4: 1}
        X [2]byte
        Y [2]int
        Z []float64
        n int

        S     []T
        Funcs = [0]func() uintptr{}
    )

    var Var813 = Funcs[int(B[Y[S[A[X[int(Z[n])]-1][n]+1].F+1]])]()

        _ = Var813
}

3. What version of the compiler are you using?  (Run it with the -V flag.)
