No, because boost.context behaves like POSIX ucontext. The app exits if
the function executed by the context ends.
You could 'link' to another context which will be executed after
finishing up the function.

What you suggest should be part of higher levels - you could find such
exception passing in boost.fiber which uses a future object for this
