Got this to reproduce. Confirmed it's from debug + LTO in the release profile. Disabling either one results in a successful build.

For now, we should drop LTO option. It is more valuable to retain debugging symbols for profiling rpc-perf itself

5 is merged to master and resolves the build issue on my test system
