this is not how asymmetric coroutines are defined - a asymmetric coroutine
has to return to its
resumption point while suspended

your code line 25 looks strange

coroutine::pull_type default_coroutine = coroutine::pull_type(std::move(
default_coroutine));

Is it a bug of Boost.Coroutine2? If not, how can I change this code to work

instead of using coroutines I suggest to use class execution_context from
boost.context
(fucntions like symmetric coroutines)

the constructor requires a function which will be executed in side the
coroutine
