Hello,

I am throwing an exception from a packaged_task, and then trying to catch it with f.get() (where f is a unique_future); it doesn't work, the program just terminates with:

terminate called after throwing an instance of 'boost::exception_detail::clone_implboost::unknown_exception' what(): std::exception

Is there a simple example somewhere, or could someone provide one, that makes clear how this mechanism is supposed to work? The Threads documentation does not show how to do this...

Try replacing throw MyException with BOOST_THROW_EXCEPTION(MyException()). You'll need to #include .

The page at http://beta.boost.org/doc/libs/release/libs/exception/doc/current_exception.... explains why you get a boost::unknown_exception.
