[issue27305] Crash with "pip list --outdated" on Windows 10 with Python 2.7.12rc1

Thanks Tim.

To clarify, the only 2 places that pip calls ctypes is to get the user application directory (and we've confirmed that doesn't error when called direct from Python), and in the vendored colorama package (which we removed and still got the crash, so it's not that).

So as far as we can tell, the crash is occurring from pure Python code, which as the OP pointed out, should not occur. The issue has also been confirmed as not happening with 2.7.11.

If anyone can suggest a way for the OP to get better information out of Python as to where the problem is occurring, I'm happy to debug further with him in the pip code in order to reproduce the issue.
