opcode create always return zero address if no require check

[JeremyX2022]

Version of Hardhat

What happened?

    function func1(bytes memory code) public {
        address addr;
        assembly {
            addr := create(callvalue(), add(code, 0x20), mload(code))
        }
        emit Deployed(addr);
    }

    function func2(bytes memory code) public {
        address addr;
        assembly {
            addr := create(callvalue(), add(code, 0x20), mload(code))
        }
        require(addr != address(0));
        emit Deployed(addr);
    }

I'm using remix connected to a local hardhat node network.
Providing any same creation code to these 2 functions, the results are different. func1 always results address(0) while the func2 is OK.

Minimal reproduction steps

Try this code:

I think this is more of a Solidity question.

This seems ... odd.

The only difference I can see between the two calls is that func1 will return address(0) if there is problem in create, while func2 will revert.
