Hi:

        Can someone tell me if the foll. derivation is valid in
performer (version 2.2):

        class XXX : public pfDCS, public YYY
        {

                public:
                    XXX() {}
                    virtual ~XXX() {}

        }

        class YYY
        {
                    public :
                    YYY() {}
                    virtual ~YYY() {}
        }

I am having trouble deleting the scene graph containing a node of type
XXX in the DBASE process. My program crashes with dbx showing the crash
at "virtual ~XXX() {}" in the call to 'realfree()'. Purify gives
FMM (freeing mismatched memory) at this line. I haven't overriden the
'new' and 'delete' operator for class XXX coz' it will anyway be
allocated in shared memory due to pfDCS as its parent , so the DBASE
process should be able to access its instance. The actual program is
based on the above class hierarchy with some data members which I make
sure are in shared arena (pfGetSharedArena()).

Thanks for any insight.
