Maybe the very first address is somewhere without debug info?
Maybe. But in any case, the very last is inside the program:
procedure TForm1.BtnConnectClick(Sender: TObject);
var
  pc: PChar;
begin
  pc := nil;
  ReAllocMem(pc, 16);
  ConnectDB;
  BtnConnect.Enabled := False;
  BtnDisconnect.Enabled := not BtnConnect.Enabled;
  BtnConnect.Enabled := False;
  GrQuery.Enabled := True;
  GrSerialTest.Enabled := True;
  GrSmallTests.Enabled := True;
  AllowQueryButtons(False);
end;

The problem is that the stackdump permamently stops resolving, once this happens.

Since you are on 1.1
yes in Vista WIN32 but not in my current development platform: Windows server 2003 x64
Lararus 0.9.31.
please install the package LeakView - then go to tools menu and open the leak view window
load the data
I've installedthe package leakview but it does not help really:
.

there is a button "resolve". select the exe that leaked. it is a new feature. it SHOULD resolve any address for which symbols exist
