TClientDataSet.XMLData leaking memory

Question

I´ve done a simple php script that returns a exactly xml datapacket from a mysql server over the web, based on the ClientDataset.CommandText property.

procedure TMainDataModule.AbertasAfterOpen(Dataset: TDataset);
begin
  DataSet.Tag := 0;
end;

procedure TMainDataModule.AbertasBeforeOpen(DataSet: TDataSet);
begin
  if Dataset.Tag = 0 then
  begin
    DataSet.Tag := 1;
    with DataSet as TClientDataSet do
      XMLData := myWebService.XMLDataPacket(CommandText);
  end;
end;

MyWebService is a simple class to post the CommandText to the php script, decode/encode64 the xml and return the data.

It works ok, but madExcept/FastMM reports memory leaks in ClientDataset.SetXmlData.

I cant see why, any ideas?

Thanks in Advance.

What is it reporting exactly? – Mason Wheeler Jul 02 '13 at 14:41 — Mason Wheeler, Jul 02 '13 at 14:41

in Delphi XE, the WebService had a memory leak which should be solved in DXE2. Which version are you using? Maybe it's not the ClientDataSet, but the WebService in your case too?

My WS is custom made with indy components, and i´m using BDS2006. If you check the paste.bin you will verify it occurs inside clientdataset. Thanks for your time. – José Eduardo Jul 03 '13 at 10:50
