Fatal Python error: ffi.from_handle() detected that the address passed points to garbage

[rq4w7z]

When I execute

proxybroker find --types HTTP HTTPS --lvl High --countries US --strict -l 10

I receive

Fatal Python error: ffi.from_handle() detected that the address passed points to garbage. If it is really the result of ffi.new_handle(), then the Python object has already been garbage collected

on last version from pip and from this repository.

Windows 8.1 x64, Python 3.5.1
cffi versions 1.5, 1.6

Until tomorrow no way to check on Win8x64 (but everything is fine on Win7x32).
However, it seems that this error is not ProxyBroker, but in pycares/cffi on x64.

Two suggestions:

1. Try to install an old pycares version: pip install pycares==1.0.0. Then execute the specified command with the option --log DEBUG, and post here the output from the console:

   proxybroker --log DEBUG find --types HTTP HTTPS --lvl High --countries US --strict -l 10.

2. Try execute code from the documentation aiodns. It was completed without errors?

[constverum]

Found the source of the error.
A complete solution in the next release pycares.

Temporary solution: use pycares 1.0 or download the wheel of pycares 2.0 from appveyor and install it:
pip install pycares -f path_to/pycares-2.0.1-cp35-cp35m-win_amd64.whl

[constverum]

The problem is solved. You can use the latest version of pycares!
