On the latest commit in the master branch during the cargo +nightly bench execution I get the following error:

<some logs are omitted>

error: could not compile `grcov` (bench "output") due to previous error
warning: build failed, waiting for other jobs to finish...

Seems like the function interface was changed without fixing the corresponding benchmarks.
