Hello, within w_get_sdp function in modules/sdpops/sdpops_mod.c } else { avp_val.s.s = pkg_malloc(sdp->raw_sdp.len); avp_val.s.len = sdp->raw_sdp.len; if (avp_val.s.s == NULL) I do not find anywhere where avp_val.s.s variable is freed. So I attach two possible patches to solve that in two different ways. Kind regards, Vicente.
