ethers-solc: compiling USDT on v0.4.18 gives out error

[joshieDo]

Trying to build USDT on foundry with solc v0.4.18 results in the following crash that can be traced over to the json line below.

the output is a valid one (acquired on the traces), it's just cant be deserialized for some reason

ethers-solc/src/compile/mod.rs

    /// Run `solc --stand-json` and return the `solc`'s output as the given json
    /// output
    pub fn compile_as<T: Serialize, D: DeserializeOwned>(&self, input: &T) -> Result<D> {
        let output = self.compile_output(input)?;
        Ok(serde_json::from_slice(&output)?)
    }

error:

➜  testdir git:(master) ✗ forge build --use 0.4.18

Error:

thanks for this
could you try dumping the json in/output via ETHERS_SOLC_LOG=in=in.json,out=out.json and perhaps try parsing them separately from a formatted json, that should highlight the serde issue I think
