I noticed that when I use the deal() function to mint some tokens to an address for testing an ERC20 contract the forge test command gives me the MemoryLimitOOG error, but suppose I use a mint function implemented in the ERC20 contract itself to mint the tokens then forge test works fine.

This gives me the mentioned error while running forge test

import {Test, console2, StdStyle} from "forge-std/Test.sol";
import {ERC20} from "../src/ERC20.sol";

contract BaseSetup is ERC20, Test {
    address internal alice;
    address internal bob;

    constructor() ERC20("Name", "SYM", 18) {}

    function setUp() public virtual {
        alice = makeAddr("alice"); 
        bob = makeAddr("bob");

        console2.log(StdStyle.blue("When Alice has 300 Tokens"));
        deal(address(this), alice, 300e18); //using deal function
    }
}

//Test Contracts here

Using deal() function

And this runs perfectly while running forge test

import {Test, console2, StdStyle} from "forge-std/Test.sol";
import {ERC20} from "../src/ERC20.sol";

contract BaseSetup is ERC20, Test {
    address internal alice;
    address internal bob;

    constructor() ERC20("Name", "SYM", 18) {}

    function setUp() public virtual {
        alice = makeAddr("alice"); 
        bob = makeAddr("bob");

        console2.log(StdStyle.blue("When Alice has 300 Tokens"));
        _mint(alice, 300e18); //_mint is an internal mint function implemented in the ERC20 contract.
    }
}

//Test Contracts here

I’m wondering what could be the possible issue here. And how is it possible to resolve this?

I tried searching about this issue on the internet to no avail. I updated foundry to the latest version, cleared cache but nothing solves the issue.
