// Issue 17588: internal compiler error in typecheckclosure()
// because in case of Func.Nname.Type == nil, Decldepth
// is not initialized in typecheckfunc(). This test
// produces that case.

func T(fn F) {
    func() {
        fn(nil)  // If Decldepth is not initialized properly, typecheckclosure() Fatals here.
