Unai Uribarri commented on AXISCPP-343:
---------------------------------------
An optimization to do the swapping in 4 byte blocks:
long *p1 = (long*)pObj;
long *p2 = (long*)pNew;
size_t i = size * sizeof(mapItem) / sizeof(long) / 2;
while (i)
{
long c = *p1;
*p1 = *p2;
*p2 = c;
++p1;
++p2;
--i;
}

> 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.
