Comparing function pointers may yield unpredictable results

[yantao0527]

Description

Comparing function pointers may yield unpredictable results due to potential differences in the address space layout of functions across program executions

Environment

• Compiler version: 0.8.x
• Target EVM version (as per compiler settings): No restrictions
• Framework/IDE (e.g. Truffle or Remix): Remix
• EVM execution environment / backend / blockchain client: None
• Operating system: None

Steps to Reproduce

contract C {
    function f() internal {}
    function g() internal {}

    function test() public pure returns (bool) {
        return C.f == C.g;
    }
}

Hi, this is a duplicate of https://github.com/ethereum/solidity/issues/13969 and since Solidity version 0.8.24 the compiler issue a warning about it.
