Actually, I'm essentially trying to figure out how situations like
that are arising. I'm not
using resize, because it reshapes the array when adding to any
dimension other than
the first. At "the end of the day" I want to enlarge an array without
leaving any
"references" dangling.

Thanks for the suggestion!
