Comment (by snaury@…):

 In my opinion boost.context is too low level for this, for example
 boost.context doesn't know anything about exceptions (and boost.coroutine
 does), besides calling C++ ABIs from assembler would be too tedious, and
 there's just nothing platform-dependant about it (more compiler or libc++
 dependant). At the same time boost.coroutine has its own abstraction,
 `coroutine_context`, where `coroutine_context::jump` would be easy to
 modify: declare and call `__cxx_get_globals()` (similar to the way
 boost.log already does) and save/restore the exception information.
