You are wrong. It does not compile, neither in delphi, nor in FPC.
D is not found, because 'A' resolves to the local a, and then the
search is stopped.
-----------------------------------
unit a;
interface
Var
D : Integer;
implementation
end.
-----------------------------------
unit b;
interface
uses a;
Type
T = Record
C : integer;
end;
Implementation
Procedure Doit;
Var
A : T;
begin
A.C:=1;
A.D:=2;
end;
end.
