5285,problem about boost::asio::ip::tcp::resolver,gong yiling <gongyiling3468@…>,chris_kohlhoff,"    one day i found a bug in my project, that's one of async_resolve's callback never called. i checked this problem and repeat this problem as following program:

{{{

#include ""stdafx.h""
#include <boost/asio.hpp>
#include <boost/bind.hpp>
#include <boost/system/error_code.hpp>
#include <stdio.h>
using namespace boost::asio;
using namespace boost;
class client
{
public:
	client(io_service& ios):
	m_ios(ios),
	m_resolver(ios)
	{
		ip::tcp::resolver* resolver = new ip::tcp::resolver(m_ios);
		delete resolver;
		ip::tcp::resolver::query query(""www.baidu.com"",""80"");
		m_resolver.async_resolve(query,boost::bind(&client::handle_resolve,this,_1,_2));
	}
	void handle_resolve(const system::error_code& ec,ip::tcp::resolver_iterator it)
	{
		puts(""see me?"");
	}
	io_service& m_ios;
	ip::tcp::resolver m_resolver;
};

int _tmain(int argc, _TCHAR* argv[])
{
	io_service ios;
	client* c = new client(ios);
	ios.run();
	return 0;
}
}}}
i digged into the source code( in function boost.asio.detail.resolver_service.destroy ) it seems when i delete a temporary created resolver, the resolver's work service will be stopped. and thus client::handle_resolve will never be called.
                                                                 thx
