Comfused... Please help

I am trying to check the network status in the 'thread' with
IcmpSendEcho function.
Here is my sample code;


// PingLeak.cpp
//

#include "stdafx.h"
#include <stdio.h>
#include <winsock2.h>
#include <iphlpapi.h>
#include <icmpapi.h>
#include <process.h>
#pragma comment(lib, "iphlpapi.lib")
#pragma comment(lib, "ws2_32.lib")

// Thread Stopper
BOOL bStopThread = FALSE;

void SendPing()
{
char SendData[32] = "SendData";
const DWORD dwReplySize = (sizeof (ICMP_ECHO_REPLY)) + sizeof
(SendData);

BYTE* pReplyBuffer = new BYTE[dwReplySize];
memset(pReplyBuffer, 0, dwReplySize);

ULONG ipaddr = inet_addr("127.0.0.1");

HANDLE hIcmpFile = IcmpCreateFile();
DWORD dwReturn = IcmpSendEcho(hIcmpFile, ipaddr, SendData,
sizeof(SendData), NULL, (LPVOID)pReplyBuffer, dwReplySize, 1000);

delete [] pReplyBuffer;
IcmpCloseHandle(hIcmpFile);

return;
}

unsigned __stdcall PingThreadFunc(void* pArgument)
{
while (!bStopThread)
{
SendPing();
printf("SendPing\n");
Sleep(100);
}

_endthreadex(0);
return 0;
}

int _tmain(int argc, _TCHAR* argv[])
{
DWORD dwThreadId = 0;
HANDLE hPingThread = (HANDLE)_beginthreadex(NULL, 0, (unsigned int
(__stdcall *)(void *))PingThreadFunc, NULL, 0, (unsigned
int*)&dwThreadId);

Sleep(3*60*60*1000); // wait for 3 hours

if (NULL != hPingThread)
{
DWORD dwWait = WaitForSingleObject(hPingThread, 20000);
if (WAIT_OBJECT_0 == dwWait)
CloseHandle(hPingThread);
}

return 0;
}



------------------------------------------

When running this program, PrivateBytes of this process in taskmanager
increase continuously.
I tested running sample for 2 days, but the memory leaking found.
Strange to say, memory leaking repro in Windows 7 only.

I already know some issue that published by Microsoft,
http://support.microsoft.com/kb/2384321

But a example in above page is different with my sample.

Can anyone help me solve this issue ?

What other (Windows) operating systems have you tried?

Is your Windows 7 installation a clean one - no 3'rd party software?

Have you tried Windows 7 SP1?

Thanks for your reply.

What other (Windows) operating systems have you tried?
Yes,

XP SP3 -> works fine
Server2003 SP2 -> works fine
Windows 7 (Non-SP) -> leaking

Windows7 (SP1) -> (not yet)

Have you tried Windows 7 SP1?
No...
I'll try it soon.

I think it's clean. Except sound driver and graphic driver, I set up a
minimal environment...

I'll try it soon.
I've tried the revised version of your code that you posted in another
group on W7 SP1 and I can't see any noticeable leak.

Dave, thank you for you confirmation. It is very useful information.
I've setup my test bed with Windows7 SP1.

On Windows7 (non-SP), I tried to collect memory usage and other
counter.
I confused that the privatebytes counter did not stop increasing.

Have you tried Windows 7 SP1?
No...
I'll try it soon.
I've tried the revised version of your code that you posted in another
group on W7 SP1 and I can't see any noticeable leak.

Dave, thank you for you confirmation. It is very useful information.
I've setup my test bed with Windows7 SP1.
On Windows7 (non-SP), I tried to collect memory usage and other
counter.
I confused that the privatebytes counter did not stop increasing.
... and what was your finding with SP1?

Unfortunately, privatebytes could not stop increase on SP1...
