Humm, what about the ptr value of ppp_pcb->rx->in_head and ppp_pcb->rx->in_tail in this case ? I guess we might need to call ppp_free_current_input_packet() before releasing the ppp pcb in ppp_delete(), and will do because this is totally harmless, but this will be better if the memory leak issue is solved with facts :-) Sylvain
