As already written, I susepct there is a missing "public:" in the above
class listing.

Moreover, the usual patterno for assignment operator is:

  A & operator=(const A &)

Moreover, if the member-wise copy is OK, and if each data member is a RAII
class that frees its own stuff, you should rely on C++ compiler default
implementation of copy constructor , assignment operator, constructor and
destructor.

In other words, in your case, this should do OK:

<code>

class A
{
public:
     //
     // Compiler generated default ctor, copy ctor, operator= and dtor are
OK.
     //
    stdext::hash_map<int,int> m_member;
};

</code>

Note that STL containers are very well composable together.
If you use std::vector instead of MFC CArray, this code will work fine:

<code>

    A item;
    std::vector<A> test;
    test.push_back(item);
    test.push_back(item);
    test.clear();

</code>
