// - All tests of out-of-line bounded allocation overruns need to have
// another big out-of-line allocation following it. This
// distinguishes "the buffer is too small" from "the bits on the
// wire asked for more than the type allowed".
// TODO(kulakowski) Change the tests to check for more specific error
// values, once those are settled.
