Lighthouse error: failed to parse manifest at `/build/source/Cargo.toml`

[bohendo]

Context

I want to use lighthouse, but it fails to build. The error says expected a boolean or an integer in profile.release.debug and, indeed, the value of this field in the's Cargo.toml is a string. At least, it is in the unpacked source archive that my system is trying to build.

Steps to reproduce

Loading the devShell from the following flake reproduces the problem.

$ uname -a
Linux mycpu 6.1.77 #1-NixOS SMP PREEMPT_DYNAMIC Mon Feb  5 20:13:03 UTC 2024 x86_64 GNU/Linux

$ cat flake.nix
{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/11cd405226b6663b1ba2073dc7d8b0d7a78175d9"; # 240209
    utils.url = "github:numtide/flake-utils/04c1b180862888302ddfb2e3ad9eaa63afc60cf8"; # v1.0.0
    ethereum.url = "github:nix-community/ethereum.nix/e428579838f13a897a41ec75dffda027cc51df3c"; # 240220
  };

  outputs = inputs: with inputs;
    utils.lib.eachDefaultSystem (system: let
      pkgs = import nixpkgs {
        inherit system;
        config.allowUnfree = true;
      };
    in {
      devShells = {
        default = pkgs.mkShell {
          buildInputs = with pkgs; [
            ethereum.packages.${system}.lighthouse
          ];
        };
      };
  });
}

Before submitting

• [X] I have attached links to the documentation, and possibly related issues and discussions.

This value in Cargo.toml is "line-tables-only" which is valid according to Cargo docs. How is the rust version determined for building lighthouse? Could it be too old?

[bohendo]

Lighthouse does build successfully if I use the input

    ethereum.url = "github:nix-community/ethereum.nix/978775c6a309ec9c98c706c56fff004a9f83d525"; # 231025

So something introduced in the last couple months seems to not work. Looks like there was a bit of a re-org, so hard to tell what it was exactly.

A binary-ish search through the history of this repo suggests commit 24d141dac0cc09c851fa32ad564a9fc67d887d6c is the culprit.
