Not a bug. The same is done for file input -- CRLF is changed to LF before tokenizing. Should this be the same? python3 -c 'print(bytes("""\r\n""", "utf8"))' b'\r\n'

No, but:
eval(r'print(bytes("""\r\n""", "utf8"))')
should be. (And is.)
What I believe you and Walter are missing is that the \r\n in the eval strings are converted early if you don't make the enclosing string raw. So what you're eval-ing is not what you think you are eval-ing, hence the confusion.
