ethers.js: Including “from” in call returns incorrect data [fyi: infura/geth issue]

Hi, I am sorry for this vague issue description, but this bug I have been seeing recently is really confusing to me:

Basically, I have one solidity contract function that should return my current ETH balance or ERC20 balance using “0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE” for ETH.

    function getTriggerValue(address _account, address _coin, uint256, bool)
        external
        view
        returns(uint256)
    {
        if (_coin == 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE)
            return _account.balance;
        IERC20 erc20 = IERC20(_coin);
        return erc20.balanceOf(_account);
    } 

Now the bug only happens if I call this function with coin="0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE" to query my own ETH balance.

So it does work for my account if I use any ERC20 address , but not our hardcoded ETH signal.

My Account: 0x203AdbbA2402a36C202F207caA8ce81f1A4c7a72

The BUG: I always get a nonsense value returned if I use my account address and make a call to the function from ethers.js using the following code

The Nonesense ETH Balance:

I also cross-checked this on Remix for my account and the result is the same nonsense:

What confuses me about this bug:

As soon as I use the exactly same code in ethers but just a different account address (I tried my friend’s) everything works as expected and I got the correct result for his account balance.

I also cross-checked on Remix and the result is correct:

This looks too weird for me to dig further, so I wanted to bring it to your attention. I believe Remix uses ethers.js too, which might explain why my results match 1:1 between the two environments.

Maybe you can help?

If you wanna give it a try, here is the stuff you need:

Solidity Interface to function I get the bug for:

pragma solidity ^0.6.0;

interface TriggerBalance {
    function getTriggerValue(address _account, address _coin, uint256, bool)
        external
        view
        returns(uint256);
}

Deployment address of TriggerBalance on ropsten: 0xaf4c11A90e98D0C5ecFb403C62Cc8Dfe8DF11030

My EOA address where I find the bug: 0x203AdbbA2402a36C202F207caA8ce81f1A4c7a72

Try maybe with your own EOA address and see if you get the bug or not.

Otherwise here is my friend’s address where the bug does not occur, oddly: 0xe2A8950bC498e19457BE5bBe2C25bC1f535C743e
