------- Comment #5 from rguenth at gcc dot gnu dot org  2010-06-22 11:16 -------
gimplification is bogus:

    switch (1) <default: <D.2122>, case 1: <D.2096>>
    {
      char x[0:D.2106] [value-expr: *x.0];

      saved_stack.1 = __builtin_stack_save ();
      try
        {
          <D.2096>:
...
        }
      finally
        {
          __builtin_stack_restore (saved_stack.1);
        }

but pre-tree-ssa we didn't get it right either.
