Hi Mustafa,

You're probably seeing the segfault because the buffer you passed to async_send is invalidated before the send completes (due to vector reallocation).

So you need to ensure that the buffer remains valid until the async_send completion is invoked, for instance your container could be managed by a shared_ptr that is passed to the completion handler.

Best regards,
