Unable to override compiler options for contracts in node_modules

[theonekeyg]

Version of Hardhat

1.22.17

What happened?

I have a set of smart contracts that use npm package for some contract dependencies. One of the smart contracts in the npm package is failing the optimizer, therefore if I want to have optimizer enabled for my contracts, I have to somehow disable optimizer for failing contracts (because fails on optimizer revert the whole compilation).

I created a very simplistic repo showcasing the error, there I put exact setup that I face, I import the contract that does not suffer from optimization failures from the package that contains a contract that does fail. The result is that the whole optimization (and therefore compilation) step is failing, even thought I don't import the failing contract directly.

I try to use solidity.overrides to disable optimizer for the problematic contract, but it does not seem to produce any effect, the compilation still fails.

Here's my hardhat.config.ts

 const config: HardhatUserConfig = {
  solidity: {
    compilers: [
      {
        version: "0.8.28",
        settings: {
          optimizer: {
            enabled: true,
            runs: 200,
          },
          viaIR: true,
        },
      }
    ],
    overrides: {
      "node_modules/@entangle_protocol/oracle-sdk/contracts/EndPoint.sol": {
        version: "0.8.27",
        settings: {
          optimizer: {
            enabled: false,
          },
        },
      },
    },
  },
};

Like I said this does not produce any effect, even in logs with --verbose it shows that it does not use compiler from overrides.

hardhat:core:compilation-job File '/home/keyg/tmp/hardhat-overrides-bug/node_modules/@entangle_protocol/oracle-sdk/contracts/EndPoint.sol' will be compiled with version '0.8.28'

Minimal reproduction steps

Clone the repo https://github.com/theonekeyg/hardhat-overrides-bug and run:

1. yarn install
2. yarn hardhat compile
3. Observe error of failing Yul optimizer
