This looks like a gimplifier bug.
In .orginal:
        if (objc_exception_try_enter (&D.2385);
        _setjmp ((void *) &D.2385.buf) != 0;)
          {
            {
              struct objc_object * D.2383;

              D.2383 = objc_exception_extract (&D.2385);
              if (objc_exception_try_enter (&D.2385);
              _setjmp ((void *) &D.2385.buf) != 0;)
                {
                  D.2386 = objc_exception_extract (&D.2385);
                }
              else
                {
                  {
                    struct objc_object * exc;

                    exc = D.2383;
                    made_catch++ ;
                    OBJ_TYPE_REF(objc_msgSend;SAVE_EXPR <exc>->0) (SAVE_EXPR 
<exc>, 
_OBJC_SELECTOR_REFERENCES_1);
                  }
                }
            }
          }
        else
          {
            thrower ();


in .gimple:
        objc_exception_try_enter (&D.2385);
        D.2387 = _setjmp (&D.2385.buf);
        if (D.2387 == 0)
          {
            thrower ();

Someone should test 4.0.x also.
