You will need to post the trace especially the call signalling messages to determine what has gone wrong..

Subject: [h323plus] Crash in Ptlib...........

Simon

After 8-10th times of placing and ending call (without restarting
application) my Application crashes in ptlib in file asner.cxx at line 2079
(Below at line no.6 for your reference)
Crashes are at both Local and Remote side on same line


1  PASN_Choice & PASN_Choice::operator=(const PASN_Choice & other)
2  {
3   if (&other == this) // Assigning to ourself, just do nothing.
4     return *this;
5
6   if(choice!=NULL)
7   {
8       delete choice;
9       choice = NULL;
10   }
11
12   PASN_Object::operator=(other);
13
14   numChoices = other.numChoices;
15   names = other.names;
16   namesCount = other.namesCount;
17
18   if (other.CheckCreate())
19     choice = (PASN_Object *)other.choice->Clone();
20   else
21     choice = NULL;
22
23   return *this;
24 }



I am using this in my Loadcapabilities function for H.263 CIF Image Size

     capabilities.RemoveAll();        //called only once
     AddAllCapabilities(0, 0, "*");     //called only once
     AddAllUserInputCapabilities(0, 1); //called only once

     preferenceorder.AppendString

(H263_CIF);
     preferenceorder.AppendString(H263_QCIF);
     preferenceorder.AppendString(H263_4CIF);
     preferenceorder.AppendString(H263_16CIF);
     preferenceorder.AppendString(H261_CIF);
     preferenceorder.AppendString(H261_QCIF);
     SetVideoFrameSize(H323Capability::cifMPI);
capabilities.Reorder(preferenceorder);
