macOS: unexpected EOF reading a line #3605
Description
Describe the bug
Nix has failed to build on darwin with this log.
https://hydra.nixos.org/build/119296096/nixlog/1
It did succeed afterwards, so unless someone recognizes what's the problem in the log, it's ok to close this and move on.
The failure happens in test case tests/user-envs.sh, with the last couple of lines being:
29 store paths deleted, 0.01 MiB freed
+ test -e /private/tmp/nix-build-nix-2.3.4.drv-0/nix-test/store/8fid272lbh1milx38cni6wi6dx7v8z7b-foo-1.0
+ '[' -e /private/tmp/nix-build-nix-2.3.4.drv-0/nix-test/store/kzm50sz0sp6gsvav10kx8xasppw0yrql-foo-2.0 ']'
+ nix-env -e '*'
