Use ReallocatePool instead of allocating then copying wherever applicable AllocateCopyPool(AllocationSize, *Buffer) will copy "AllocationSize" bytes of memory from old "Buffer" to new allocated one. If "AllocationSize" is bigger than size of "Buffer", heap memory overflow occurs during copy. One solution is to allocate pool first then copy the necessary bytes to new memory. Another is using ReallocatePool instead if old buffer will be freed on spot.
