In for statements (for i, v := range ...) the iteration variable(s) is reused i.e., at each iteration, the value of the next element in the range expression is assigned to the iteration variable; v doesn't change, only its value changes. Hence, the expression &v is referring to the same location in memory. Hence exporting pointer to loop variable is not recommended and it often a bug-risk. It is recommended to use the memory by indexing it (arr[i]) if it's a slice or array, or by creating a copy (v := v) instead.

Bad practice

results := make([]*int, 0)
for i, p := range []int{1, 2, 3, 4, 5} {
    results = append(results, &p) // bug-risk
    fmt.Println(&p)
    switch {
        case i%3:
            intRef = &p     // bug-risk
            intStr.x = &p   // bug-risk
        default:
    }
}

Recommended

results := make([]*int, 0)
for i, p := range []int{1, 2, 3, 4, 5} {
    p := p
    results = append(results, &p)
    fmt.Println(&p)
    switch {
        case i%3:
            intRef = &p
            intStr.x = &p
        default:
    }
}
