prevent undefined behaviour in S_maybe_multideref()
The first pass that calculated the size of the required structure
started with a NULL pointer, and incremented that pointer as the space
needed for the multideref sequence was accumulated.
This pointer math (adding to a non-object pointer) is undefined
behaviour in C, even if the pointer is not de-referenced.
Changed to use an integer index instead.
