Try this:

---
import std.stdio;

void delegate() global;

void foo(scope void delegate() del)
{
      global = del;
}


void f()
{
      {
          char[5] bar = "hello";
          foo((){writeln(bar);});
      }
}

void smashStack() {
     uint[1000] dummy = 0xbadcab1e;
     asm { nop; }
}

void main()
{
      char[7] baz = "goodbye";
      f();
      smashStack();
      global();
}
