HI,
        I have a problem with pfMalloc when I am using pfMalloc to create
a shared memory. Here is my simple code:

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

while SharedData is a typedef structure, and inside SharedData, there is a
Class container:

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

Where Class "Console" is an abstract class, the array is to store derived
class from "Console".
        I can create an object and assign it into the array, but after
that, when I want to access the object's public function like this:

        shared->console[0]->

It is always segmentation falut.
I am using "CC" to compile and "cc" to link the object programs on IRIX
6.2 Indy.

Any comment are welcome.
Thanks in advance.
David Chan
