If an indexed array has no available slots after its last index, +=() will overflow the last index, and set into an illegal negative index, effectively prepending values instead of appending them.
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. Chet -- ``The lyf so short, the craft so long to lerne.'' - Chaucer ``Ars longa, vita brevis'' - Hippocrates Chet Ramey, UTech, CWRU c...@case.edu http://tiswww.cwru.edu/~chet/
