11290	Boost future continuations failing on OS X	chappedm@…	viboes	"I have a problem with using boost future continuations via then(). I am building Boost 1.58 for both Linux 64-bit and OS X 64-bit. I have the following code that executes correctly:


{{{
        auto future = session().join(m_realm);
        uint64_t session_id = future.get();
        TRACE(trace_logger) << ""session joined: session_id "" << session_id;
}}}

However if I re-write it as:

{{{
        auto future = session().join(m_realm).then(
            [](boost::future<uint64_t>) {
                uint64_t session_id = future.get();
                TRACE(trace_logger) << ""session joined: session_id "" << session_id;
            }).wait();
}}}

then the continuation is never called and I am stuck waiting on this future to be resolved for indefinitely. Seems to be a data race of some kind. Unfortunately, I don't have a minimal test case to reproduce the issue yet."	Support Requests	closed	To Be Determined	thread	Boost 1.57.0	Showstopper	worksforme
