The following problem exists in python3.3.0 and python3.3.1rc1.

From the command line it works:

root@dhcp175-40-red:~ # python3
Python 3.3.1rc1 (default, Apr  5 2013, 18:03:56) 
[GCC 4.2.1 20070831 patched [FreeBSD]] on freebsd10
Type "help", "copyright", "credits" or "license" for more information.
>>> from distutils.util import byte_compile

From script it hangs:
root@dhcp175-40-red:~ # cat /tmp/ 
from distutils.util import byte_compile
files = [

byte_compile(files, optimize=1, force=None,
             prefix=None, base_dir=None,
             verbose=1, dry_run=0,

# python3 /tmp/
--> Now it hangs forever, if I press Ctrl+D, I get:
Traceback (most recent call last):
  File "/tmp/", line 1, in <module>
    from distutils.util import byte_compile
  File "/usr/local/lib/python3.3/distutils/", line 9, in <module>
    import imp
  File "/usr/local/lib/python3.3/", line 28, in <module>
    import tokenize
  File "/usr/local/lib/python3.3/", line 37, in <module>
    __all__ = token.__all__ + ["COMMENT", "tokenize", "detect_encoding",
AttributeError: 'module' object has no attribute '__all__'

I was unable to replicate this bug with clean builds of either Python3.3.0 and Python3.3.1rc1 on either Linux or OSX. I assume you also meant Ctrl-C, since there is no reading from standard input occurring in this script.  Without further data such as platform/vendor information, an strace, or a secondary confirmation of this behavior, I would suggest closing this bug.

My test environment on Linux was Ubuntu 12.10, Linux 3.2.0-34-generic, 2.15glibc.  On OSX, I'm running 10.7.5 with the latest command line build tools.

No, I meant Ctrl+D.
I use FreeBSD-10.

Hi Dmitry, since I can't replicate your issue, can you provide any more context from GDB and/or strace/ktrace?  Thanks!

Can’t reproduce (linux 3.12).  If someone on FreeBSD can reproduce the bug, please reopen this ticket.
