I will do my best, but I really cannot promise any time slot for looking into the issue. Perhaps it is the time to revisit Tom's libcontext [1]? The number of #ifdefs in tge current coroutine code makes eyes pop out, and I am afraid with the new issue we would be forced to add "#ifdef __APPLE__" to this horrible mess.
This way we should be immune to future boost::context changes. The drawback is, we are on our own if there is a new architecture to support. On the other hand, how often a new architecture becomes popular enough to care about it? To sum up: I would switch to libcontext and stop worrying.
