Thanks for the report. I think it's reasonable to check for overflow here,
and not to use the convention that negative subscripts count back from the
end.
I think if INTMAX_MAX - last_index < elements_to_append , bash should
just error (error similar to setting to a readonly variable).
It should be an assignment error similar to
a[-1]=value
to an empty array.
