What am I doing wrong. I can't call the delegate twice with anything in between.

----
void func(){ writefln("func"); }

void main(){
  void delegate() dg;
  dg = toDelegate(&func);
  dg(); // np
  //writefln(dg.ptr," ", dg.funcptr,"."); // Error: Stack Overflow @ second dg call
  //writefln(); // Error: Access Violation @ second dg call
  dg();
}
