[New-bugs-announce] [issue8558] StringIO().truncate causes zero-bytes in getvalue()

[holger krekel]

New submission from holger krekel <holger.krekel at gmail.com>:

Running the attached file with python3.1.1 works fine, all assertions pass.  Running it with 3.1.2 gives me this output: 

$ python3.1.2/bin/python3.1 stringio_fail.py
Traceback (most recent call last):
  File "stringio_fail.py", line 12, in <module>
    assert s == "world", repr(s)
AssertionError: '\x00\x00\x00\x00\x00world'
