With r47564, Coverity 980630 reports: Negative array index read. @Michael,
since this code is probably still fresh in your mind, maybe you could take a
look at it? I didn't see your name listed in Coverity yet, so below is the
meat of the code that leads to the warning:
1724 if (transport_info == NULL) {
1725 transport_info = se_alloc0(sizeof(transport_info_t));
CID 980630 (#1 of 1): Negative array index read
(NEGATIVE_RETURNS)var_tested_neg: Assigning: "transport_info->media_count" = a
negative value.
1726 transport_info->media_count = -1;
...
1905 /* Free the remaining hash tables not used */
var_assign: Assigning: signed variable "n" = "transport_info->media_count".
At conditional (16): "n < 4" taking the true branch.
1906 for (n = transport_info->media_count; n < SDP_MAX_RTP_CHANNELS; n++)
1907 {
negative_returns: Using variable "n" as an index to array
"transport_info->media".
1908 rtp_free_hash_dyn_payload(transport_info->media[n].rtp_dyn_payload);
1909 }
