ICallback::Clone() fails to set parent

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile example
2. Use any function which calls GetParent (e.g. "list_fun()")
3. Observe assertion error on m_pParent == NULL


What is the expected output? What do you see instead?

List of functions, see above.


What version of the product are you using? On what operating system?

Linux ntjk 2.6.37.6-0.9-desktop #1 SMP PREEMPT 2011-10-19 22:33:27 +0200 x86_64 
x86_64 x86_64 GNU/Linux
muParserX 2.1.0

Please provide any additional information below.

Can be fixed by making GetParent a const function and using 
SetParent(GetParent()) in Clone() on cloned instance first; tested, solves the 
problem, function works as intended.

The defect is in the example.cpp file. I forgot to update the function 
definitions there when i changed it in the rest of the code. Instead of using 
parameterless contructors Clone should invoke the copy constructor.

virtual IToken* Clone() const
{
  return new FunListFunctions(*this);
}

I Fixed the sample code, the rest of the codebase was already doing it right.
