Julien: I'm working on enhancement of debug traces on visit_decref(). Are you still able to reproduce the crash in 2019?

I failed to reproduce the bug in a virtual environment with:

* Python 2.7.14
* pip 8.1.2
* cffi 1.7.0

$ virtualenv -p python2 venv
Running virtualenv with interpreter /usr/bin/python2
New python executable in /home/haypo/venv/bin/python2
Also creating executable in /home/haypo/venv/bin/python
Installing setuptools, pkg_resources, pip, wheel...done.

$ venv/bin/python -m pip install pip==8.1.2
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at

You are using pip version 8.1.2, however version 19.2.3 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
