sphinx shows an EOF error when using python2.7 from the trunk. Last successful build was with the 2.7.13 release.
It looks like this is triggered only when using the parallel mode in sphinx. I haven't yet worked on this issue, Sphinx is v1.4.9.
sphinx-build -b html -d _build/doctrees -n -j 4 . _build/html
Running Sphinx v1.4.9

Using git bisect, I identified that Sphinx started to fail since the commit 12536bd261ba95cd2748f3d7d47768742a6ffa7a which comes from bpo-30775.
I reported the bug to Sphinx:

This seems like a bug, or least poor design, in Sphinx. It tries to read from pipes from processes that it knows are already dead (because it joined them!).

wontfixing since Sphinx has fixed their code.

FYI The bug has been fixed in the Sphinx development branch (HEAD of master): https://github.com/sphinx-doc/sphinx/issues/4061#issuecomment-330140975 I validated that Sphinx master now works as expected on Python 2.7.14.
