Scope of constructor initialisation list

[Pantokrator]

Hi all,
I've got a question about the scope of the constructor initialisation
list. First of all, let me explain my classes:

// *************** *************** *************** ********
class CThread
{
CThread(){};
CThread(CMyThre adFunctor *pThreadFunctor )
{
...
};
};
// *************** *************** *************** ********
class CMyThreadFuncto r
{
....
};
// *************** *************** *************** ********
class CMyThread : public CThread
{

CMyThreadFuncto r *m_pThreadFunct or;

public:

CMyThread()
: CThread(m_pThre adFunctor = new CMyThreadFuncto r(this)) <<<<
SCOPE-1
{
//CThread(m_pThre adFunctor = new CMyThreadFuncto rIMO(this));
<<<<SCOPE-2

}
};

When I init the CThread object using the constructor init list
(SCOPE-1), my CThread object runs fine without a problem. If I init
CThread within the constructor (SCOPE-2), my CThread calls the
destructor straight after initialisation and I suspect that it is
related to the scope of the object. I even tried the following but
without any luck:
class CMyThread : public CThread
{

CMyThreadFuncto r *m_pThreadFunct or;
CThread

public:

CMyThread()
: CThread(m_pThre adFunctor = new CMyThreadFuncto r(this)) <<<<
SCOPE-1
{
//CThread(m_pThre adFunctor = new CMyThreadFuncto rIMO(this));
<<<<SCOPE-2

}
};

{
mainThread=(m_p ThreadFunctor = new
CMyThreadFuncto rIMO(this)); <<<<SCOPE-2

}

};
Could you please tell me what am i doing wrong here and what is the
sccope of the two lines?

Thanks

This initializes base CThread

{
//CThread(m_pThre adFunctor = new
CMyThreadFuncto rIMO(this)); <<<<SCOPE-2

This creates temporary non named object of type CThread
and calls it's destructor at ';'.
