add another check to remove the one additional Ncomp = Ncomp_new;

assume the evaluation of conditions doesn't change code behavior

this evaluates to A(BA)*

    label:             <- the original code
        stuff A
    if (condition) {
        stuff B
        goto label
    }

this evaluates to (AB)+

    do {
        stuff A
        evaluate condition (in case stuff overwrites variables used in it)
        stuff B
    } while (condition)

This will lead to one more "B" than the original code

So change it to this

    do {
        stuff A
        evaluate condition (in case stuff overwrites variables used in it)
        if (condition) {
            stuff B
        }
    } while (condition)
