Arghhhh, to much Delphi :\. All confusion is related to my Delphi
knowledge. I took it as fact also for FPC.

For Delphi even for XE2 in record case there is no difference between RTTI
and INIT table. RTTI table for record does not contains any information
about unmanaged fields -,- . Just pure copy of INIT table. (Maybe in Delphi
exist only INIT table in that case)

Output for attached example FPC is 2, output for Delphi is 1. In Delphi
rich RTTI information about unmanaged fields for records is stored in
different place.

=== example ===
type
  TR = record
    x: integer;
    s: string;
  end;

begin
  WriteLn(PTypeData(GetTypeData(typeinfo(TR)))^.ManagedFldCount);
  readln;
end.
