Problem with Dedicated key on Release request

Gurux DLMS for ANSI C++

After updating to the latest version of gurux.cpp (I had a very old version), i'm having problems debuging because an assert.
The problem is that after AARQ, the m_DedicatedKey stored in the GXCipher has position advanced.
Then in GXAPDU:233->GXByteBuffer:406, when trying to set the dedicated key, an assert throws because pos is already it's max size.
I'm able to reproduce this behaviour every time. Can you fix it?

Hi,

Our customers are using the dedicated key all the time. Can you add a hex trace from AARQ and AARE so I can check what is happening?

BR,
