Multiple AVs in 15.2.12

[JuergenS]

Hi Alexandre,

when I exit the IW debug dialog after starting an application in the browser and closing it again, I now get an AV with IW 15.2.12.
In the application itself I get AVs in many places, I am now back to IW 15.2.11.

C++ Builder 10.4

System.pas

procedure TObject.Free;
begin
// under ARC, this method isn't actually called since the compiler translates
// the call to be a mere nil assignment to the instance variable, which then calls _InstClear
{$IFNDEF AUTOREFCOUNT}
  if Self <> nil then
    Destroy;
{$ENDIF}
end;
