import ( "fmt" "golang.org/x/mobile/exp/audio/al" ) func main() { fmt.Println("Hello, playground") err := al.OpenDevice() if err != nil { fmt.Println("failed to open device " + err.Error()) return } defer al.CloseDevice() }
The line defer al.CloseDevice() causes the crash. Removing that line allows the program to run without printing an error.
defer al.CloseDevice()
I expected not to see a crash.
