The program is:

package main
func main() {
    x := [1]int16{0}
    y := make([][2]int, 1)
    var s *string
    _ = func() {
        (x)[y[(func() int)(nil)()][len(*s)]]++
    }
}

$ go build -compiler=gccgo src.go
src.go:6:6: error: incompatible type for field 2 in struct construction
  _ = func() {
      ^
src.go:6:6: error: too few expressions for struct
src.go:7:34: error: expected pointer
   (x)[y[(func() int)(nil)()][len(*s)]]++

gc compiles successfully.
