This will prevent the fix in rust-lang/rust#65198 from regressing.
The benchmark is quite short-running, taking roughly 3x the time of
helloworld
. That's more than enough to detect regressions; prior to the fix it would have taken more than 100x longer.@dtolnay, @alexcrichton: this benchmark is based on this test case. I hope that is ok. Let me know if you have ideas on how to improve this.
