This is tt.d:

import std.stdio;

string ctfe(){
    int[] ctfe2(int n){
        int[] r=[];
        if(n!=0) r~=[1]~ctfe2(n-1);
        return r;
    }
    return ctfe2(2).length == 2 ?
     "hello from runtime!" : "hello from compile time!";
}

void main(){
    pragma(msg,ctfe());
    writeln(ctfe());
}

$ dmd -run tt;
hello from compile time!
hello from runtime!
$

The ctfe'd result is generally longer than the correct one. The example works as expected if ctfe2 is moved outside ctfe.

A workaround is to make ctfe2 a 'static function'.
