sys.addaudithook(None) breaks the REPL

[devdanzin]

Bug report

Bug description:

Running the code below exits the interpreter if using PyREPL, results in an infinite loop in basic REPL and breaks IDLE. Nevertheless, it might be a case of "just don't do that then".

import sys
sys.addaudithook(None)

It might be necessary to hit Enter again to see this behavior.

In basic REPL, the loop prints (and doesn't seem to be interruptible with Ctrl+C):

Exception ignored in audit hook:
TypeError: 'NoneType' object is not callable

In Windows with PyREPL, the error is (and then the interpreter exits):

In Linux with PyREPL the error is (and then the interpreter exits):

It also breaks IDLE:
