32/64bit Delphi compiler inconsistency or bug?

[Nikos 0]

Hi,

TLine = class(TObjectList)
  ...
  procedure Add(const X: Real); overload;
  procedure Add(const n: Integer); overload;
  ...
end;

In Delphi 12 (Update 1), after the change of TList.Count to NativeInt from Integer, calling the Add procedure like this NewLine.Add(NewLine.Count - 1) calls the Real overloaded procedure in 64bit Delphi, and the Integer one in 32bit Delphi.
Am I doing something ambiguous, is it a Delphi compiler inconsistency or a bug?

Thanks!

NativeInt is 64-bit on Win64 so Integer overload is not appropriate (too small) there. If you want to force it to Integer overload you will have to typecast Integer(NewLine.Count - 1)

... or change the type in the method: Add(const n: NativeInt);

You're right, I should have paid more attention when migrating to Delphi 12 🙂
