Go Up to Error and Warning Messages (Delphi)

This occurs when using a type constraint in a record that may not be compatible with record rules (no inheritance, no methods).

program E2569;

TGenRec<T> = record //E2569 Fix: use TGenRec<T : record> = record
    case Boolean of
      True: (A: T);
      False: (B: Pointer);
