Well, to be more specific: It seems to come from the shell, that then invokes the compiler. Nevertheless it is stored in the output variable. In my case it contains: /nix/store/9ywr69qi622lrmx5nn88gk8jpmihy0dz-bash-4.4-p23/bin/sh: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) /nix/store/9ywr69qi622lrmx5nn88gk8jpmihy0dz-bash-4.4-p23/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8) gcc (GCC) 9.3.0 Copyright (C) 2019 Free Software Foundation, Inc.
