Description
When I dynamic create Object of TFileStream

TFileStream * f = new TFileStream1 ("img.bmp",fmOpenRead);

afrer close Application CodeGuard Not detected this memory leak


I try Create Chil class for TFileStream

class TFileStream1: public TFileStream {
  public :
  __fastcall TFileStream1(AnsiString  as, unsigned short w):TFileStream(as,w){}
  __fastcall virtual  ~TFileStream1() {
    OutputDebugString(AnsiString().sprintf("~TFileStream").c_str());
  }

and check  ~TFileStream1()  -- not be called
Steps to Reproduce:
1. Enable CodeGuard


2. type the code

class TFileStream1: public TFileStream {
  public :
  __fastcall TFileStream1(AnsiString  as, unsigned short w):TFileStream(as,w){}
  __fastcall virtual  ~TFileStream1() {
    OutputDebugString(AnsiString().sprintf("~TFileStream").c_str());
  }
};
//---------------------------------------------------------------------------
__fastcall TfmBitmap::TfmBitmap(TComponent* Owner)
  : TForm(Owner)
{
TFileStream * f = new TFileStream1 ("img.bmp",fmOpenRead);

}

Please see QC#29277.

CodeGuard can not detect memory leak which is allocated by Delphi(RTL/VCL) library.
