isConstructor() error in Initializable.sol

[elishadrion]

Compiling or using the Initializable.sol isn't possible due to an error in the isConstructor() function. The function in question and the error are highlighted below ;

  /// @dev Returns true if and only if the function is running in the constructor
  function isConstructor() private view returns (bool) {
    // extcodesize checks the size of the code stored in an address, and
    // address returns the current address. Since the code is still not
    // deployed when running a constructor, any checks on its code size will
    // yield zero, making it an effective way to detect if a contract is
    // under construction or not.
    uint256 cs;
    assembly { cs := extcodesize(address) } <--
    return cs == 0;
  }

This is invalid in Solidity as in address is a reserved keyword.

Given the context, it seems it should be ;

    uint256 cs;
    address _addr = address(this);
    assembly { cs := extcodesize(_addr) }
    return cs == 0;

Thank you for reporting! This will be fixed in the 2.7 release.

It was fixed in #1413.
