# Fix Travis write errors on Clang builds. These write errors occurred after
# a Travis update to new Trusty images on Dec. 12th 2017. The reason for these
# write errors is unknown. Using the deprecated builds did not fix the problem.
# Setting 'filter_secrets: false' as suggested here
# https://github.com/travis-ci/travis-ci/issues/4704#issuecomment-321777557
# fixes the problem.
