Emacs crashes after MacOS 15.4 upgrade

[rrajath]

Hi,
I recently upgraded my MacOS to Sequoia 15.4 and emacs started crashing. I was getting the following error:

nix/apps/aarch64-darwin on  HEAD (3c2df18) [$✘!+] 🥋 (q 9 (no description set)) took 9s

I see that libgccjit does exist in the /nix/store/... path.

I tried overriding it in packages.nix like so:

  (emacs.override {
            withNativeCompilation = true;
            libgccjit = pkgs.libgccjit.overrideAttrs (old: {
              NIX_CFLAGS_COMPILE = "-O3 -march=native";
            });
          })

and a few other variations of these, but nothing helped.

Is anybody else facing the same issue? Any help to resolve this would be greatly appreciated.

I am on 15.4 with a working Emacs. I think I had to use emacs instead of emacs-unstable to get it to build, and I turned off my launchd agent.
