I would like to see who can make Python have a fatal crash with the most creative code. This means that when the program runs, Windows for example, will take over and pop up with something like “IDLE has stopped working”, or Linux will do whatever Linux does when a program crashes.

Rules:

1. This must be made in Python 2.7 or above (So old bugs aren't exploited that have been fixed in future versions of Python).
2. The definition of "crash" is "make IDLE or Python exit in an unintended way." This does not mean "make IDLE or Python halt and give a traceback". This also means exit, sys.quit, abort etc are not valid answers. For example, this will not be accepted:

```
import sys
try:
     print c # Crashes Here, as c is not defined.
 except NameError, SyntaxError:
     print "Oh No!"
     sys.exit()

```
3. Making Python stop responding is not accepted.
4. The code must be explained on what it does to crash. A link to a bug report is fine.

The most upvoted answer after 10 days wins!
Begin!!

**EDIT:**
May I make it clear that the objective is **not to make Python just halt executing the program** with a traceback. The objective is to make Python completely crash or stop working. This means that if this task is successfully accomplished, Windows would give this (I'm not crashing Word here, it's just an example of what should happen for a different program):
