async_set_up_wakeup passes ASYNC_SENTINEL_EVENT (a NULL pointer) to async_register_event. On epoll_ctl/kevent failure, the error path unconditionally called destroy_async_event on the sentinel, which dereferences NULL and crashes. Guard the destroy call the same way async_unregister already does. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
