Unsafe type in Spring.pas

[Jacek Laskowski]

The compiler warns about the "unsafe type" in the Spring.pas file, I don't know if this is a sensible report or a false report.

[dcc32 Warning] Spring.pas(8999): E1046 Unsafe type 'TFieldTable'

procedure MoveManaged(source, target, typeInfo: Pointer; count: Integer);
type
  TFieldInfo = packed record
    TypeInfo: PPTypeInfo;
    Offset: NativeInt;
  end;

  PFieldTable = ^TFieldTable;
  TFieldTable = packed record
    Size: Integer;
    Count: Integer;
    case TTypeKind of   <====================== in this line
    tkArray:  ( ElemType: PPTypeInfo );
    tkRecord: ( Fields: array[0..0] of TFieldInfo );
  end;

  function GetFieldTable(typeInfo: Pointer): PFieldTable; inline;
  begin
    Result := PFieldTable(PByte(typeInfo) + PByte(typeInfo)[1] + 2);
  end;

Compiler Version? Platform? Any compiler option that differ from those in the package for that compiler version?

Delphi 10.3.2, x86

Output warning → Unsafe type → True

I first set Unsafe Type → Error, but then I had a compilation error just, after change to True I get warning only. I don't know if it's important, but I report.

Probably bogus - that warning is not enabled in my package anyway.
