You have applied the TypeInfo standard procedure to a type identifier which does not have any run-time type information associated with it.


program Produce;

  type
    Data = record
    end;

  var
    v : Pointer;

begin
  v := TypeInfo(Data);
end.

Record types do not generate type information, so this use of TypeInfo is illegal.


program Solve;

  type
    Base = class
    end;

  var
    v : Pointer;

begin
  v := TypeInfo(Base);
end.

A class does generate RTTI, so the use of TypeInfo here is perfectly legal.
