[Stackless] Stackless 2.6.2/Win crash with very short script

[Stefan Reich]

Hi all,

I have been playing around with Stackless a bit. In doing so, I came 
across what I assume is a bug in Stackless.

This script:

-----
# crash_stackless.py
# this crashes in:
# Python 2.6.2 Stackless 3.1b3 060516 (release26-maint, Apr 14 2009, 
21:19:36) [MS
# C v.1500 32 bit (Intel)] on win32

import stackless

def f():
 stackless.channel().receive()

stackless.tasklet(f)()
stackless.run()
-----

makes python.exe crash. Here's the Windows debug info (German, sorry):

Any thoughts? The code seems innocent enough to me. I have seen other 
examples work, including some that sent data through a channel, so 
apparently the bug only appears if you write your script in a certain way.

Cheers,
Stefan
