Sounds to me like a good fix would be to change the parse code to
turn ksh arrays into zsh arrays (incrementing non-negative numbers)
OR to turn the values into an internal representation of offset and
length at parse time (though you may have to leave -1 unchanged if
you don't know the length).  This way, the C code would be able to
handle the more flexible indexing values properly (the zsh values)
without affecting ksh compatibility.
