The compiler's behaviour is ambiguous. It doesn't compile like this:

class A  {  };

template<typename T> void Func(const T&)   {   }


void OnStart()
  {    
    A* const a= NULL;
    Func(a);   // 'a' - constant variable cannot be passed as reference
  }

But if you declare the pattern like this, it compiles:

template<typename T> void Func(const T*const&)   {   }

Thank you! Corrections have been made to all of your messages.

"2016.07.30 00:26:29 Core 1 occupied by another terminal". - check in task manager - you have test agents running. Maybe either from your local network another terminal is counting something or from the Cloud someone is counting.

I don't use cloud, terminal is opened alone. Agents are Ready. Rebooting the terminal solves the problem for a while.

Are other terminals using local agents? Very likely several terminals are running simultaneously and they can't share resources - test agents.
 
Karputov Vladimir:
Are the local agents being used by other terminals? Very similar to multiple terminals running at the same time and they cannot share resources - test agents.
There is only one computer on the local network and only one terminal is running on it. Rebooting terminal helps. I.e. terminal thinks its agent is occupied by it.
 
fxsaber:
There is only one PC on my local network and only one terminal is running on it. Restarting the terminal helps. I.e. terminal considers that its agent is busy by itself.

What operating system? What is the build of the terminal? (This information is in the first three lines in the "Log" tab after restarting the terminal).

Do you let the terminal fully complete the test? Or interrupt testing? Or the testing is interrupted by errors in the code? Do you use a pure MQL5 code or do you use Win API calls?

 
It seems to be about the sometimes unclosed windows from visual testing. Playback, however, is not working. It's working now.
