[issue21546] int('\0') gives wrong error message

[Kurt Rose]

New submission from Kurt Rose:

int() ignores everything after a null byte when reporting an error message.

Here you can see an example of how this manifests, and why could be a problem.

Python 2.7.6 (default, Nov 10 2013, 19:24:18) [MSC v.1500 32 bit(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> int('a')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: 'a'
>>> int('\0a')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: ''
>>> int('abc\0def')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: 'abc'
