I tried both suggested solutions but still have the same errors
boost::function<void(int)> f = boost::bind( DPC::Print1, &x, 2 );
t.async_wait( boost::bind( Component::Method1, &y, 10, f, &t ) );
or
t.async_wait( boost::bind( Component::Method1, &y, 10,
boost::protect(f), &t ) );
It seems like boost::protect does not not affect this expression at all.
Maybe I'm doing something wrong.
Thank you in advance,
