[python-committers] "Invalid symmetric difference expression" on Travis-CI

Hi,

I've just got this weird error on Travis-CI (the build itself is still marked green, which is great :-D): https://travis-ci.org/python/cpython/jobs/254906991

""" $ set -e if ! git diff --name-only $TRAVIS_COMMIT_RANGE | grep -qvE '(\.rst$)|(^Doc)|(^Misc)' then echo "Only docs were updated, stopping build process." exit fi ./configure --with-pydebug make -j4 make -j4 regen-all clinic changes=git status --porcelain if ! test -z "$changes" then echo "Generated files not up to date" echo "$changes" exit 1 fi

fatal: Invalid symmetric difference expression 8a8d28501fc8ce25926d168f1c657656c809fd4c...84e0e7a063215809b81e59ab7f59c8bf44492aa8 Only docs were updated, stopping build process. """
