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
' 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?

Florian
