--- Comment #4 from mengjun wei <wei_mj at 139 dot com> ---
GCC 11.2 no longer allow return_value and return_void be both defined, may this
restriction be removed? This makes the co_return statement necessary:
CTask workflow_work(CTaskScheduler::RawPtr scheduler,
co_comm_ctx::co_comm_workflow* workflow, const char* buf, int len)
{
        co_comm_resp_impl::ptr response(new co_comm_resp_impl);
        co_await co_comm_ctx::short_req_task::create(workflow, 1, buf, len,
response);
        co_await co_comm_ctx::short_req_task::create(workflow, 2, buf, len,
response);
        co_await co_comm_ctx::resp_task::create(workflow,
response->result.c_str(), response->result.length());
        co_return 0;
}
