-------------------------------------------------

Hi Mark,

why do we use a memset here?? And why we use a virtual destructor here in RPC??

> The function Axis_Create_* (in the following example, the mapItem
> object) in the stubs generated by wsdl2ws java tool generates a SIGSEGV
> when tring to enlarge an array of objects
>         mapItem* pNew = new mapItem[nSize];
>         memcpy(pNew, pObj, sizeof(mapItem)*nSize/2);
>         memset(pObj, 0, sizeof(mapItem)*nSize/2);
>         --> delete [] pObj; <-- SIGSEGV
> memset clears the virtual table pointer of the mapItem objects and the delete operator crash.
