Whereas clang-14 builds pass. I am considering this as a waiver.
The problem is with clang-13. you may keep the above patch which is
adding support for gcc-12.

We will stop building with clang-13 and we will upgrade our toolchains to
clang-15 (when released and current clang-nightly builds are in production)
and gcc-12 builds are running in staging. We would like to bump versions soon.
