Summary: Python 2.4.0 crashes with a segfault, EXAMPLE ATTACHED

Initial Comment:
Running the attached example crashes python 2.4.0 on linux (segfault) and Windows. Python is compiled on Debian Linux 3.0r3 (Woody). On Windows XP, I used the MSI installer downloaded from python.org

This may be a problem with the regular expression module, but I'm not sure. Please assign a new category if it appears as a regexp bug.

This bug causes permanent crashes in my new WEB applications. Old apps not using regexp and PyMeld seem to run correctly.

Thanks for 2.4.1.

Partially reproduced on Windows XP.  (Using the stock 2.4.
0 msi)  

Just loading it in IDLE and hitting F5 (run), it prints None, 
as though it had succeeded perfectly.

Typing in the commands from index.py by hand, I can get 
it to give me the "encountered an error;  Tell Microsoft?" 
box, but IDLE only restarts instead of actually crashing.

There seems to a problem between the __getattr__ and 
the __setattr__ in PyMeld.  

"""
>>> p=Meld(open('player.html','rb').read())
>>> p.StreamURL1.value
'mss://stream.url'
>>> p.StreamURL2
<PyMeld.Meld instance at 0x00B455F8>
>>> p.StreamURL2.src
'mms://stream.url'

>>> v=Video()
>>> v.stream
's'
>>> p.StreamURL1.value=v.stream
>>> p.StreamURL1.value

>>> ================================ 
RESTART 
================================
>>>

What do you do to make it crash?  "python index.py"?

It doesn't fail for me with CVS HEAD.
