[bluexg7]

var m = make(map[string]string)
m["a"] = "ccc"

from := []interface{}{[]int{7,8,9},2,3, m, errors.New("aaaa")}
var to []interface{}

copier.CopyWithOption(&to, &from, copier.Option{
	IgnoreEmpty: false,
	DeepCopy:    true,
})

from[0].([]int)[0] = 10

fmt.Println(to)

this code will panic
