I use nix-darwin and have enabled nix in ~/.stack/config.yaml. Earlier today I did a sudo nix-collect-garbage -d then many things begin to break.

Minimum reproducible example:

stack new mwe
cd mwe
stack build

mwe> configure (lib + exe)

Error: [S-7282]
       Stack failed to execute the build plan.

       While executing the build plan, Stack encountered the error:

       [S-7011]
       While building package mwe-0.1.0.0 (scroll up to its section to see the error) using:
       ...
       Process exited with code: ExitFailure (-6)

A problem that I have never seen before this garbage collection.

Adding gmp as a nix package in stack.yaml does not help and result in the same error message. Neither will nix-shell -p gmp.

nix:
  enable: true
  packages:
    - gmp

I do have gmp-with-cxx here. Why can't stack find it? Why a wrong hash was used?

Deleted ~/.stack/setup-exe-cache, stack clean --full and then stack build works. Not sure if I have to do this every time after nix-collect-garbage.
