HI,
        I am sorry to mislead the problem about pfMalloc and object
container to assigning object to object container. Since I have try to do
like this, actually I can assign object into object container, but the
problem is I can't access the data filed of this object. Here is the whole
story:
===================================================

class Console: public pfObject {
         
protected: int dummy;
         
public:
        int getDummy() { dummy = 2; return dummy; }
        int getOne() { return 1; }
        virtual void interaction()=0;
}

class Dervied_from_Console : public Console
{
        ...
public: virtual void interaction() { ... }
        ...
}

typedef structure {
        ...
        Console *console[10];
        ...
} SharedData;

SharedData *shared = pfMalloc(sizeof(SharedData),pfGetSharedArena());

shared->console[0] = new Dervied_from_Console();

printf("first try: %d\n",shared->console[0]->getOne()); // this statement is ok

printf("second try: %d\n",shared->console[0]->getDummy()); //Segnmentation fault

======================================================

I do the allocation of shared memory before pfConfig(), and I have try to
use malloc() to allocate memory in non-performer appilication. In that
case, both "printf" work fine.

Any comments are welcome.
