Research direction
Start with the benchmark case for grouping 1e9 rows and compare its behavior before and after dplyr 1.0.0. Read the linked upstream dplyr issue 5291 for the reported internal error and current resolution. Done means the benchmark behavior is restored or the incompatibility and required next step are documented.
