Fixed issue with parsing packed structure. 32 and 64 bit packed values won't be parsed correctly due to bad pointer manipulation

If you're after more supporting information. Please consider what happens in opack.c, line 472. The pointer p is never modified by opack_decode_obj because it's using (p)+=8 instead of (*p)+=8. This results in an infinite loop as it processes the same offset over and over
