Here are the steps to reproduce this:

• Compile and link Python against readline version 7.0 or higher.
• Add

set enable-bracketed-paste on

to your ~/.inputrc

• Start python and paste the following two lines. Make sure to use a terminal emulator that supports bracketed paste (most modern ones do). You'll need to type enter after pasting the lines.

a = 1
a

You get something like

>>> a = 1
a
  File "<stdin>", line 1
    a

^

SyntaxError: multiple statements found while compiling a single statement

It does work, however, if you paste something that has a newline but is a single statement, like

(1,
2)

Fixing this in the right way might not be so easy, due to the way that compile('single') is over-engineered. A simple fix would be to disable bracketed paste in the Python shell.

I tested this with Python 3.6.3. I was not able to get the git master to compile, so I couldn't test it there.
