断点执行socket通信程序，有部分程序不执行，断点符号显示成白色的小圈圈？

如题，红色的是不执行的部分程序

// SOCK_STREAM is for TCP, SOCK_DGRAM is for UDP
	s = socket( AF_INET, SOCK_STREAM, 0 );
	if( s < 0 )
	{
		AfxMessageBox("failed connect1");
		goto leave;
	}
	else
	{
		AfxMessageBox("successed connect1");
		goto leave;
	}
	
	
	sin.sin_family		= AF_INET;
	sin.sin_addr.s_addr	= tmp;
	sin.sin_port		= htons(CMDPORT);

	//connect net
	if ( connect( s, (const struct sockaddr *)&sin, sizeof(sin) ) < 0 )
	{
		AfxMessageBox("failed connect2");
		goto leave;
	}
	else
	{
		AfxMessageBox("successed connect2");
		goto leave;
	}

	
	if( send( s, buf, 100, 0 ) < 0 )
	{
		AfxMessageBox("send failed ");
		goto leave;
	}
		
leave:
	if(pBuf)
		delete []pBuf;
	if(s >= 0)
		closesocket(s);
	
	WSACleanup();
}

这部分不执行
sin.sin_family = AF_INET;
sin.sin_addr.s_addr = tmp;
sin.sin_port = htons(CMDPORT);

//connect net
if ( connect( s, (const struct sockaddr *)&sin, sizeof(sin) ) < 0 )
{
AfxMessageBox("failed connect2");
goto leave;
}
else
{
AfxMessageBox("successed connect2");
goto leave;
}


if( send( s, buf, 100, 0 ) < 0 )
{
AfxMessageBox("send failed ");
goto leave;
}

goto leave;

不管s = socket( AF_INET, SOCK_STREAM, 0 );
的执行结果如何，都直接跳到
leave:
if(pBuf)
delete []pBuf;
if(s >= 0)
closesocket(s);

WSACleanup();
所以红色的部分不会执行...

不建议使用 goto 语句~~

但是，我这是拷贝的一段程序啊，原来的那个程序就可以运行啊,怎么回事呢？
