The code that makes me wonder something is wrong is this one:

{$mode objfpc}
{$h+}
procedure TheB(var aTheA: string);
begin
aTheA:=aTheA+'A';
end;
function TheA(): string;
begin
//Result:='';
TheB(Result);

Var
C : String;
begin
C:='B';
C:=TheA;
C:=TheA;
Writeln('= "',C,'"');
end.
For me (win32, FPC 2.6.2) the output is identical (= "A") whether or
not Result in TheA() is initialised manually or not. Perhaps 2.7.1
has a regression here if it differs for you?
It is not a regression. 2.7.1 has the Delphi compatible behaviour.
Seems that we should add a remark here:
