Description

If a method declaration like this

procedure a(b: dword);

with an implementation like this:

procedure TMyClass.a(b: cardinal);
begin
end;

exists, class completion works as expected: It does nothing.

But if you add an overload directive to the declaration and press Shift+Ctrl+c, class completion creates an additional declaration with b: cardinal and an implementation with b: dword.

Steps to Reproduce:

Create a unit with this code:

unit Unit1;

interface

uses
  Windows;

type
  tmyclass = class
  private
    procedure a(b: dword); overload;
  end;

implementation

procedure tmyclass.a(b: Cardinal);
begin
end;

end.

This code is correct and compiles because DWord=Cardinal.

Now press Shift+Ctrl+c. The IDE will add one new declaration and one new implementation like this:

unit Unit1;

interface

uses
  Windows;

type
  tmyclass = class
  private
    procedure a(b: dword); overload;
    procedure a(b: Cardinal);
  end;

implementation

procedure tmyclass.a(b: Cardinal);
begin
end;

procedure tmyclass.a(b: dword);
begin
end;

end.

This code does not compile because it contains two erros:
1. The second declaration does not have the overload directive
2. Since dword = cardinal the overload is not allowed.
