While I won't say the ASN code is completely bug free (a debugged program is merely on for which the failing condition has not yet been found) it is also highly unlikely to be the source of your problem. The last bug was found in July, 2004!
What does tend to happen is the ASN code does a LOT of small memory allocations so is extremely susceptible to heap corruption. However the act of corrupting the heap could, unfortunately, be ANYWHERE. And at risk of causing offense, the most likely place is in your code. After all a lot of people use H323plus and even more use PTLib and are not seeing this crash.
This type of problem is notoriously difficult to find. The reason is that the crash point can have absolutely nothing to do with the cause of the crash which is in a completely different function and possibly even different TIME. The only way to fix them is divine inspiration and very good coding practices. The most common reasons are the "dangling pointer" and the "uninitialized pointer". If you don't know those terms go find a textbook and a better university.

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

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.

Hi,
Does anyone managed to run endpoint based on h323plus that listens on port TCP 80? This will help h323plus based endpoint to work like Skype in more regulated networks.
Regards, Zarko
Zarko
The solution is a little more complicated then simply listening on port 80. The endpoint must connect, and keep alive a connection to another device on that devices TCP port 80 (or 443). Registration (RAS) in H323 is generally via UDP on port 1719 and call signalling on 1720. There is a H.460 standard that will allow you to merge both RAS and Call Signalling onto one port and support NAT traversal on port 80. The standard is H.460.17 and will allow you to register, make and receive calls over port 80 (or 443) HOWEVER this will not get the media thro' which must be over UDP so open UDP ports must be found. The problem is you need minimum 2 ports (audio & video) unless you multiplex media (which is supported in H.460.19), however neither h323plus or GnuGk support it.
So besides port 80 (or 443) you need minimum a reliably open UDP port for it to fully work, now you just have to find that open UDP port and it can possibly work. :-)
Of course you will need to go implement H.460.17 & H.460.19 (with multiplexed RTP) on both the NATed Endpoint and Gatekeeper.
