[issue8256] TypeError: bad argument type for built-in operation

[Bruce Frederiksen]

New submission from Bruce Frederiksen <dangyogi at gmail.com>:

I'm getting a "TypeError: bad argument type for built-in operation" on a print() with no arguments.  This seems to be a problem in both 3.1 and 3.1.2 (haven't tried 3.1.1).

I've narrowed the problem down in a very small demo program that you can run to reproduce the bug.  Just do "python3.1 bug.py" and hit <ENTER> at the "prompt:".

Removing the doctest call (and calling "foo" directly) doesn't get the error.  Also removing the "input" call (and leaving the doctest call in) doesn't get the error.

The startup banner on my python3.1 is:
Python 3.1.2 (r312:79147, Mar 26 2010, 16:55:44) 
[GCC 4.3.3] on linux2

I compiled python 3.1.2 with ./configure, make, make altinstall without any options.  I'm running ubuntu 9.04 with the 2.6.28-18-generic (32-bit) kernel.
