Daniel Martí 618f88d847 text/template: never call reflect.Zero(nil) ... It makes no sense to try to get the zero value of a nil type, hence the panic. When we have a nil type, use reflect.ValueOf(nil) instead. This was showing itself if one used a missing field on the data between parentheses, when the data was a nil interface: t := template.Must(template.New("test").Parse(`{{ (.).foo }}`)) var v interface{} t.Execute(os.Stdout, v) Resulting in: panic: reflect: Zero(nil) [recovered] panic: reflect: Zero(nil) Fixes #21171.
