Now, this build failure happens in unstable as well. It prevents 
ocaml-ctypes (and maybe other OCaml-related packages) from migrating to 
testing.

llvm-toolchain-13 has been requested to be removed:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1017679

This is blocked by ghc, which has no fix at the moment:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1017663

The OCaml situation makes it urgent that llvm-toolchain-13 builds again.

Therefore, I am going to submit a NMU forcing usage of g++-12.
