What did you do?

1. code here:

package main

import (
	"fmt"

	"github.com/AlecAivazis/survey/v2"
)

func broken() {
	var input string
	err := survey.AskOne(&survey.Select{
		Message: "please choose:",
		Options: []string{"Option1", "Option2"},
	}, &input)

	if err != nil {
		// crash here
		panic(err)
	}
	fmt.Println(input)
}
func main() {
	broken()

}

2. garble it： garble build -ldflags="-s -w" .

What did you expect to see?

It should print what I choose.

What did you see instead?

panic:

panic: template: prompt:4:19: executing "option" at <.CurrentOpt.Value>: can't evaluate field Value in type hXCS2oWxzi9.DYdqhhUhlOQ

goroutine 1 [running]:
main.uHhC2SXRwzv()
        Oeubp4hOAGzv.go:1 +0x1b1
main.main()
        FQt7OAGNPv.go:1 +0x17

I have also come across this, although my error is slightly different:

Error: prompt failure: template: prompt:2:7: executing "prompt" at <.ShowHelp>: can't evaluate field ShowHelp in type GJB2N4R4a5.OalHLhT4uq

My survey.Question's are setup like this:

	hostname, _ = os.Hostname()

	endpointNamePrompt = &survey.Question{
		Name: "endpoint_name",
		Prompt: &survey.Input{
			Message: "Please enter a display name for this endpoint:",
			Default: hostname,
			Help:    fmt.Sprintf("Use the system hostname if you don't have a specific name (hostname: '%s')", hostname),
		},
		Validate: survey.Required,
	}

	endpointIdPrompt = &survey.Question{
		Name: "endpoint_id",
		Prompt: &survey.Input{
			Message: "Please specify an endpoint ID:",
			Default: hostname,
			Help:    fmt.Sprintf("Use the system hostname if you don't have a specific ID (hostname: '%s')", hostname),
		},
		Validate: validateID,
	}

It doesn't always replicate though, which is annoying but probably down to the nature of garble.

FWIW, I never came across this problem with Go 1.20 + garble v0.10.1 - for me it only started occurring after bumping to Go 1.21+garble v0.11.0.
