----------------------------------------
Cleaning up...
Command /usr/bin/python3 -c "import setuptools, tokenize;__file__='/tmp/pip_build_root/cffi/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-hoa0sujr-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_root/cffi
Storing debug log for failure in /root/.pip/pip.log

and subsequently totally breaks pip3, with all invocations resulting in this error:

This is almost certainly going to be pypa/pip#4253.
