The build succeeds if I use a slightly older nixpkgs that has GCC 13 in stdenv instead of GCC 14. I stubbed out all of the patches in overlays/bootstrap.nix just to be sure, but bootstrap GHC 9.6.4 still fails to build.
However, upstream Nixpkgs builds GHC 9.6.4 with a GCC 14 stdenv without this issue, and I can't see why.
