I have installed https://releases.nixos.org/nixos/22.11/nixos-22.11.4773.ea4c80b39be4/nixexprs.tar.xz and i found gcc-unwrapped version mismatch and while checking nix-tree i found that as part of nix installation wrong gcc 9.5 is installed and the NIX_CC env variable is also set to 9.5.0
Seems like because 22.11 channel dont have separate version for aarch64 it is not working but when i try to use x86_64 the gcc version is correct.
how ever when i use Channels for NixOS project(s) chhanel i am getting correct gcc version that is 9.3.0 which is mentioned in the documentation.
Steps to reproduce
Linux architecture is aarch64-linux
Install https://releases.nixos.org/nixos/22.11/nixos-22.11.4773.ea4c80b39be4/nixexprs.tar.xz
then check the gcc-unwrapped package and it is not 11.3.0 rather it is 9.5.0
which is causing
whereis gcc
gcc: /usr/lib/gcc /usr/share/gcc /nix/store/f38iyls39nx3j2am87q0ni605nb152gv-gcc-wrapper-9.5.0/bin/gcc /nix/store/q7hw7f9lldzlizrad4xaqb1cm5v4qwqh-gcc-9.5.0/bin/gcc
