gccgo(1.8) not compiling

[jeesteve]

Hi,

I could not compile this code with gccgo (1.8). I don't know if a gccgo compiler frontend issue or not. just want to let you know about :)

func (s *Supervisor) sendControl(sm supervisorMessage) bool {
  | select {
  | case s.control <- sm:
  | return true
  | case _, _ = (<-s.liveness): <- here!!!
  | return false
  | }
  | }
