The only thing I wish is that you could get memory managers to
_reliably_ fall over when you make a rookie mistake like this. I think
most of us have spent many hours sweating blood over heap corruption
bugs, at least in the days before things like Valgrind and dmalloc.
Fence-post errors can be less blatant than this.
