Thanks for the feedback! Then I suggest you report the issue to the cygwin 
Python packagers.

you are right: windows native python 3.3.3 from your link runs the program 
properly - and without crashing.

(note that stem.util.system at least uses ctypes)

Can you try with a standard Windows build?

Antoine Pitrou added the comment:

If this is a cygwin build (rather than a standard MSVC build), I'm afraid 
that's not a supported platform at all. Did you compile Python yourself?

[issue20398] stem crashes python

[R. David Murray]

R. David Murray added the comment:

For anyone else who wants to look at this: it doesn't look like stem involves 
any C code, and the 'signal' method appears to be a text-based interprocess 
communication.

Can you reproduce this with 3.3.3?  3.2 is in security-fix-only mode, and while 
a crash can be a security issue, it isn't necessarily.

[issue20398] stem crashes python

[lothar]

New submission from lothar:

setup: python 3.2 ; cygwin64 

python crashes with a stackdump, which is attached.

stem is a python controller module for tor.

stem-1.1.1 can be had from here:
https://pypi.python.org/pypi/stem/

the code is in version 2 form, but "python3 setup install" runs 2to3 on it.

this code crashes before the for statement:

#! /usr/bin/env python3

import urllib.request
from stem import Signal
from stem.control import Controller

with Controller.from_port(port=9151) as controller:
  controller.signal(Signal.NEWNYM)

for nn in range(1, 3):
  print("case %02d" % nn)
  proxy_support = urllib.request.ProxyHandler({"socks5" : "127.0.0.1:9150"})
  opener = urllib.request.build_opener(proxy_support)
  urllib.request.install_opener(opener)
  print(urllib.request.urlopen("http://www.ifconfig.me/ip";).read())
