[New-bugs-announce] [issue16741] `int()`, `float()`, etc think python strings are null-terminated

[ganges master]

New submission from ganges master:

I'm not sure if it's a bug or just an inconvenience, but when a string containing \x00 is passed to int/float/etc, they return a misleading exception:

    >>> int("abc")
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ValueError: invalid literal for int() with base 10: 'abc'
    >>> int("\x00abc")
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ValueError: invalid literal for int() with base 10: ''
    >>> float("\x00abc")
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    ValueError: could not convert string to float:

I noticed the code does actually try to handle it:
http://hg.python.org/cpython/file/39803c20c9bf/Objects/intobject.c#l1066

but still, the reported error is very misleading.
