Hi Performers,

I've a question regarding the use of pfMalloc to allocate memory for user
defined classes.

I've a class A, class B and class C as follows:

class A {
public:
        ...
        virtual void initialize() = 0;

};

class B : public A{
public:
        void initialize();
}

class C : public pfTexture{
public:
        A* a;
        static void init();
        void initialize();
}

void C::init()
{
        pfTexture::init();
        initialize();
}

void C::initialize()
{
        a = (B*) pfMalloc (sizeof(B), pfGetSharedArena());
        a->initialize(); /*----------- Get core dump here ------- */
}

When I try to run this program, I get a core dump at the placed marked.
Infact, any virtual function called by A dumps core. Can anyone point the
mistake I'm making. I'm not sure if this is totally a C++ problem or is it
in some way related to pfMalloc.

Thanks
Satheesh
