[Linphone-developers] SDP handler BUG in coreapi

[Alex Pepper]

I'm using the latest stable version of linphone: 1.0.1, 23 Mar 2005.
I've found a bug on file coreapi/sdphandler.c, in functions 
sdp_context_read_answer ().
This bug don't allow sometimes linphone to enable the input/output audio 
stream when one make a call out.
The code of sdp_context_read_answer () is:

void
sdp_context_read_answer (sdp_context_t *ctx,char *remote_answer)
{
   sdp_message_t *remote;
   char *mtype, *tmp;
   char *proto, *port, *pt, *bw;
   int i, j;
   int err;
   sdp_payload_t payload;
   sdp_handler_t *sdph=ctx->handler;

   sdp_message_init(&remote);
   sdp_message_parse(remote,remote_answer);
   if (err<0) {
       eXosip_trace(OSIP_WARNING,("Could not parse remote offer."));
       return ;
   }

...

As you can see, at line 493 "err" var is used but not initialized 
(declared at line 487).
As far as I can see, err should be set: err = 
sdp_message_parse(remote,remote_answer); at line 492.
If err is not set, sometimes, when it's random value is less than 0, the 
function return with error and the audio streaming does not start.

Hope that's help.

Alex.
