Hi,

I am using asio´s io_service::work class to prevent io_service.run()
from returning. Unfortunatly on deletion of my object the destructor of
io_service::work throws an exception:

terminate called after throwing an instance of
'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::system::system_error>
>'
  what():  mutex: Invalid argument

boost::asio::io_service::work::~work() + 22 (io_service.ipp:155)

The asio related objects are all members of my class:

[...]
private:

        io_service ioService;
        io_service::work ioWork;
        thread ioThread;
        tcp::socket controlSocket;
        tcp::acceptor acceptor;
[...]

This is how I initialize everything:

[...]
MyClass() : ioService(),
                ioWork(ioService),
                ioThread(bind(&io_service::run, &ioService)),
                controlSocket(ioService),
                acceptor(ioService),
[...]

Finally this is what happens in the destructor:

[...]
if (connected)
        disconnect();
ioService.stop();
ioThread.join();
[...]

Anyone knows how to deal with this?

Regards,

Florian
