Build failure on MacOS

MacOS build is failing with an error given below.
I'm building HEAD
Mac OS version: 12.0.1

The error seems to be from protobuf build. There was similar issue for protobuf that seems fixed https://github.com/protocolbuffers/upb/issues/212
Building protobuf HEAD worked. So, I'm not sure what exactly is causing the issue. Protobuf build had updated some system component (forgot to note that).

2 warnings generated.
