This is a API breaking change that was introduced without any deprecation warning. Updating the application code to use skipped will cause a build-break for when compiled against older version of GoogleBenchmark. There are no macros to detect the version of benchmark library.

To reproduce NA

Expected behavior All code using error_occurred should compile. A deprecation warning should be emitted a few releases prior to removing the public field from a struct.
