[Bug tree-optimization/18268] New: missed SRA of a block copy

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I think this is a regression from a previous version of 4.0.0

typedef struct
{
  void *ptr1, *ptr2;
  unsigned word;
  unsigned word_bit;
} bitmap_iterator;
void
get_call_expr_operands ()
{
  bitmap_iterator bi;
  bi.ptr1 = 0;
  bi.word = 0;
  bi.word_bit = 0;
start:
  {
    bitmap_iterator bi1 = bi;
    if (bi1.ptr1 != 0)
      goto start;
  }
}
