Build failure: Boehm-gc-8.2.6, Nixos-24.05

When trying to switch to Nixos 24.05 the boehm-gc package breaks because of invalid patch. I believe it is this patch nixpkgs/pkgs/tools/package-management/nix/patches/boehmgc-coroutine-sp-fallback.patch at 0b8e7a1ae5a94da2e1ee3f3030a32020f6254105 · NixOS/nixpkgs · GitHub that breaks, but i am not expert sadly :frowning:

System: x86_64-linux

Is this associated with the upgrade from boehm-gc-8.2.4 → boehm-gc-8.2.6?
Are there any workarounds?

I have a similar one - I think there’s multiple conflicting patches getting applied, I tried to fix with an overlay to get boehmgc to work just applying this patch. To do this I set the array to , then in the patch phase I did patch -p1 < {my-patch-here}.

However, afterwards I got a unit test failure in nix on one test (in multiple versions of nix)
