New subject: [thread]MFC based console application cause memory leak?

6 Sep 2006


      I’ve written a MFC based console application to test boost.thread library. 
However, IDE suggested that there are memory leaks in the program. All that I’
ve done is creating a class A which implements operator () and declared an 
instance of boost::thread which make use of A. How can that make memory leak? 
My IDE is vs.net 2003 and my OS is windows xp sp1.
My code is as follows:

// threadmemleak.cpp : 
//

#include "stdafx.h"
#include "threadmemleak.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#endif

#include 

class A
{
public:
	A()
	{
	}
	void operator() ()
	{
		//Sleep(1000);
	}
};


// Single application object
CWinApp theApp;

using namespace std;

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
	int nRetCode = 0;

	// Initialize MFC and display error on failure
	if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
	{
		// TODO: Correct your code so as to meet your need
		_tprintf(_T("Fatal error: MFC initialization failed\n"));
		nRetCode = 1;
	}
	else
	{
		// TODO: Write your own code
		A a;
		boost::thread thread1(a);
		thread1.join();
	}

	return nRetCode;
}

 and output of IDE is

Detected memory leaks!
