Testcase:
struct temp
{
  temp(){}
  ~temp(){}
  temp(const temp&){}
};
struct crop
{
    int ox, oy, dx, dy;
};
struct Parm
{
    temp filename;
    crop cp;
};
void Foo(Parm x);
void Bar1()
{
    Parm p;
    p.cp.dx = 0;
    Foo(p);
}
void Bar2()
{
    Parm p;
    p.cp.dy = 0;
    Foo(p);
}

the problem is that Parm's copy constructor is at line 21 which is wrong.
This is a regression from earlier 4.0's where the copy constructor was not generated lazy.
