The old code was trying to pass -Wgnu-zero-variadic-macro-arguments as part of CXXFLAGS, but it forgot the quotation marks needed around whitespace. This meant that option was ignored: https://travis-ci.org/github/google/googletest/jobs/666534177#L760 Unfortunately, the codebase is not remotely clean with respect to that warning option. It fails like this: https://travis-ci.org/github/Quuxplusone/googletest/jobs/668118135 So, remove that failing configuration from the test matrix until someone has time to look at it.
