Why

let test_overflow ctxt =
  if Sys.word_size = 32 then
    assert_raises Decoder.(Failure (Overflow ""))
                  (fun () -> Decoder.int_of_int32 "" 0xffffffffl)
  else

should overflow? 0xffffffffl = -1 on 32 bit systems - perfectly fits to int

Oh, hm. Then the test is wrong. It should test for something like 0x7fffffff, an int32 value that doesn't fot into int. (Maybe Int32.max_int?) Can you please fix it and send a PR?
