To fix this, CTFE will need to properly implement a stack for variables to be
stored on.
-------------
void bug6037(ref int x, bool b){
    int w = 3;
    if (b) {
        bug6037(w, false);
        assert(w==6);
    } else {
        x = 6;
        assert(w==3); // fails
    }        
}

int bug6037outer(){
    int q;
    bug6037(q, true);
    return 401;
}
static assert(bug6037outer() == 401);
