string - Error addressing the returned slice of a function

Question

In the next code the first Println fails on build with error slice of unaddressable value. The rest of the lines are just fine.

package main

import "fmt"

func getSlice() [0]int {
   return [...]int{}
}

func getString() string {
   return "hola"
}

func main() {
    fmt.Println(getSlice()[:]) // Error: slice of unaddressable value

    var a = getSlice()
    fmt.Println(a[:])

    fmt.Println(getString()[:])

    var b = getString()
    fmt.Println(b[:])
}

Try this code

If the first Println is commented it works. Try it out

Why is that? What I'm missing here?
