Internal compiler error on function name collision

[mathiasestolarz]

Solidity version:

0.4.24+commit.e67f0147.Linux.g++

Source code:

pragma solidity ^0.4.24;

contract SomeContract {

  uint public balance = 0;


  function balance(uint number) public {
    
  }

  function doSomething() public {
    balance(3);
  }
}

Platform:

Ubuntu 16.04.4 LTS

How to reproduce the issue:

Run a bash script that compiles the contract like this:

#!/bin/sh

solc SomeContract.sol

What was the result of the issue:

This output in the console:

Internal compiler error during compilation:
/build/solc-FodDYg/solc-0.4.24/libsolidity/analysis/TypeChecker.cpp(2260): Throw in function virtual bool dev::solidity::TypeChecker::visit(const dev::solidity::Identifier&)
Dynamic exception type: boost::exception_detail::clone_impl<dev::solidity::InternalCompilerError>
std::exception::what: Requested type not present.
[dev::tag_comment*] = Requested type not present.

What the expected behaviour is:

Correct compilation because of the different signatures the getter of the balance variable and the balance function have.

Observations:

pragma solidity ^0.4.24;

contract SomeContract {

  mapping(uint => uint) public balance;

  function balance() public {
    
  }

  function doSomething() public {
    balance();
  }
}

• In this case, the same output is shown.

Small observation here: Also breaks if the mapping and the function are called something else like "thing".
