[New-bugs-announce] [issue8847] crash appending list and namedtuple

[benrg]

New submission from benrg <benrudiak at gmail.com>:

c:\>python
  Python 3.1.2 (r312:79149, Mar 21 2010, 00:41:52) [MSC v.1500 32 bit (Intel)] on win32
  Type "help", "copyright", "credits" or "license" for more information.
  >>> from collections import namedtuple
  >>> foo = namedtuple('foo', '')
  >>> [1] + foo()

At this point the interpreter crashes. Also happens when foo has named arguments, and in batch scripts. foo() + [1] throws a TypeError as expected. [] + foo() returns (). The immediate cause of the crash is the CALL instruction at 1E031D5A in python31.dll jumping into uninitialized memory.
