F2084 Internal Error in Delphi compiler

[Kryvich 174]

Never seen such error in Delphi 12, until today:

[dcc32 Fatal Error] CompilerError.dpr(17): F2084 Internal Error: GPFC0000094-152D5B90(15290000)-0

100% repeatability.

program CompilerError;

{$pointermath on}

type
  PRec = ^TRec;
  TRec = record
  end;
  PArr = ^Arr;
  Arr = array [0..0] of TRec;

var
  P: Pointer;

begin
  P:=@PArr(P)[0];
  P:=@PRec(P)[0];
end.

(C) notme

Why would one declare an empty record?

@Lars Fosdal Meaningless synthetic code. For the compiler developers, to fix an internal error. If they visit this forum.

 

Although this information may not help you, it can help us (Embarcadero) track down the problem if and when you report the error.

The phrase when you report the error is most likely targeting the official issue tracker at https://qp.embarcadero.com/ and not this forum.

@Uwe Raabe I hope the original author (notme) of the snippet has already done this. I've posted it here as a curious fact for those interested (like me). I haven't encountered any internal compiler errors in Delphi in recent years.

 

Although, perhaps this bug has already been fixed in 12.2. (I have 12.1 CE).

No, it is not fixed.

I got that one just last week. AFAIR, it too had to do with a array[0..0] of stuff. I can't really remember much about it because I was in a rush and just worked around it
