Here's a simpler example that gives similar results:

$ py -3.3
Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:03:43) [MSC v.1600
32 bit (Intel)] on win32

>>> def broken():
...   try:
...     broken()
...   except RuntimeError:
...     broken()
...
>>> broken()
Fatal Python error: Cannot recover from stack overflow.

Current thread 0x0000058c:
  File "<stdin>", line 3 in broken
  File "<stdin>", line 3 in broken
...

Under Python 2.7.5 it just goes into an infinite loop. Under Python
3.2.5 and 3.3.2 it crashes the interpreter as shown above.

What the broken() function is doing is totally stupid: responding to a
recursion error with more recursion. However this may indicate or be
considered a bug in the 3.x interpreter.
