crash core stack

A few questions:

Is this after trying to upgrade to 1.39 or is the program that crashes strictly using 1.33.1?
What version of Asio are you using with 1.33.1?
What happened to boost/asio/impl/write.ipp?

We use version 1.33.1.

We analysed the problem and now it seems that the problem is at our side. At async_write method (see below) we give the Ccdt_TcpHandler::handleWrite as Callback method. We are not absolutely sure, but the Ccdt_TcpHandler object is deleted before the boost uses Ccdt_TcpHandler::handleWrite as Callback method.

If it is true, then we do not understand that in this case the crash has to happen in Ccdt_TcpHandler::handleWrite method, but according the core file the crash is in boost.

Now we try to avoid the Ccdt_TcpHandler object deleting before Callback.

boost::asio::async_write

( *TcpSocket, boost::asio::buffer

( pMsg->data(), pMsg->length() ),

boost::bind

( &Ccdt_TcpHandler::handleWrite, this, ID, pMsg->id(), pMsg->command(), pMsg->info(), pMsg, boost::asio::placeholders::error )

);

Closing as OP said that problem was on their side.
