Internal compiler error during compilation

[kalloc]

Hi.

I got an error on the contract compilation (contract was simplified for viewers)

library SafeMath {
  function mul(uint256 a, uint256 b) internal pure returns (uint256 c) { return 1; }
}
contract Parent  {
    string public name;

    constructor(string _name) public {
        name = _name;
    }
}

contract Test is Parent {
    using SafeMath for uint256;

    constructor() public Parent("Name") {
        uint256(1).mul(1);
    }

}

Error from console:

Internal compiler error during compilation:

Without internal everything is working

Have you tried this with any of the nightly versions on Remix? To me it seems it has been fixed since the release in one of the nightlies.

@axic hi, I didn't found this bug in remix or Linux, My ideas is a bug in clang + solidity.

@kalloc can you try the latest version? I'm pretty sure this has been fixed in the meantime.

@chriseth I don't have the problem on 0.4.24
