This bug.gen module:

component bug {

  struct foo {
    string bar;
  };

  port out foo Bug;

  task  bla {
    period    100 ms;
    codel <start>    InitBla(port out Bug) yield ether;
  };
};

generates the warning below:

Nothing dramatic, just annoying in the middle of a warning less compilation ;-)
