Thread model: posix
gcc version 4.10.0 20140516 (experimental) (GCC)
The program is:
package main
func main() {
(<-(<-make(chan chan func([1]string, float64) (chan string,
[0]bool))))([1]string{string("foo")}, 1.1)
_ = <-(([][]chan uintptr{})[(((([][]int{})[1])[(<-(<-(<-((([][][]chan chan
chan int{})[1])[1])[(<-([]chan int{})[1])])))]) + (<-make(chan int)))])[1]
}
