Nixpkgs: Darwin regressions on hydra

[jonringer]

Describe the bug
Seems that many darwin builds are now breaking suddenly. Seems to be a multitude of reasons. Just odd that it all seems to be specific to darwin.

https://hydra.nixos.org/eval/1576403

example error:

/nix/store/2kcifdkr7m14csgch00ajbz28irdwhff-bash-4.4-p23/bin/bash: /nix/store/r4fs9daiww3xcjrbdqd6av375ir8v7fn-cmake-3.16.5/bin/cmake: No such file or directory
make[2]: *** [source/blender/

I started getting build errors for Go-based packages likes sops when installing from nixpkgs-unstable on Darwin. I see the same error in the Hydra build log for sops.

# crypto/x509

Similar error appear continuously on Hydra – reference to some other package where the file suddenly appears missing or malformed. I believe there's some problem in the builder set up. Too aggressive GC (if that's even possible) or some other corruption. The errors I've seen always disappeared on restarting the builds.

EDIT: but the Security/Security.h thing is probably something different than what I meant.

FWIW - this fixed my go issues on darwin

seems related to: 060a9227c24639ca5a339fbb57b8e05a5eabb92e
reverting that commit also worked for me wrt golang on darwin.

Closing since most of these regressions were because buildGoModule https://github.com/NixOS/nixpkgs/pull/83099

Well, yes. Errors like in the OP and my post seem unrelated (e.g. blender) and appear non-deterministically for much longer time (i.e. not really recent regressions). Probably better have a separate thread now, if someone feels like investigating them deeper.
