I'm sorry I didn't read your email fully before. My BAD
 
Anyway the problem appears to be that you are opening 2 control channels on 2 different threads
 
 2:26.038  H225 Calle...er:22641e8 H245  Handle control channel
 2:26.038  H225 Calle...er:22641e8 H245  Start control negotiations
 2:26.038  H225 Calle...er:22641e8 H245  Sending TerminalCapabilitySet:
outSeq=1
 2:26.038  H245:6f3ff60      H245  Started thread
 2:26.038  H245:6f3ff60      H245  Handle control channel
 2:26.038  H245:6f3ff60      H245  Start control negotiations
 
Looking at the code I cannot see how this is even possible to do?
My Guess is that in you derived
H323Connection::OnSendCapabilitySet()
You are starting a control channel. That's not wise.
If so I would remove that segment of code from your application.

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);

The last few lines of PTRACE are

This crash is consistent. Crashes anytime after 5th call..
Your comments are needed.
