Actually it is not caused by the front-end but it is almost fixed on the tree-ssa now:
  pred<D1940> = f;
  pred<D1947>.pred = &pred<D1940>;
  pred<D1954>.pred = &pred<D1947>;
  pred<D1961>.pred = &pred<D1954>;
  pred<D1968>.pred = &pred<D1961>;
  pred<D1975>.pred = &pred<D1968>;
  pred<D1982>.pred = &pred<D1975>;
  pred<D1989>.pred = &pred<D1982>;
  pred<D1996>.pred = &pred<D1989>;
  <D2053> = f ();

Now all we have to do is remove the stores and this would be fixed.
