I can reproduce this issue on Linux with:

$ cd Doc
$ make venv
$ PATH=./venv/bin:$PATH sphinx-build -b doctest -d build/doctrees -D latex_elements.papersize= -q -W -j4 -W . build/doctest 

I get random errors:

The virtual environment uses Sphinx 2.0.1. Can it be a change in Sphinx 2 default configuration?
