Hi,
I've fixed a bug in FreePointerList.
Btw. I really don't think this is a hack - it's simply addresses the problem that dlls can have at most 2^32 bytes and therefore the system use 32-bit addresses internally thus some operations will go wrong if the memory of the dll spans over a 4GB boundary.

Thanks! I used your code with a slight modification to improve adding to the linked list and implemented missing error handling.
