[sr-dev] How to parse msg stored in the tm correctly?

Hi Ser Gurus: How to parse msg stored in the tm correctly? e.g in the reply msg, we can get the corresponding request from tm: msg = t->uas.request; The sip_msg_cloner seems copy only via/from/to/cseq/auth headers and parsed headers to the shm, right? what if we want to parse the other headers, e.g: parse_headers(msg, HDR_ROUTE_F, 0)<0) The parse_headers uses pkg_alloc, thus the parsed result is pkg_alloced and stored the tm structure, then it never get freed until tm is destoried ( but even in this case tm may call shm_free instead of pkg_free???? ) So how can we parsed the tm-stored msg and how to do it correctly?
