Only first previously deleted entry was recognized, leading hsearch_r
to think that there was no previously deleted entry. It then conluded
that a free entry was found, even if there were no free entries and it
overwrote a random entry.
This patch makes sure all deleted or free entries are always found and
also introduces constants for the 0 and -1 numbers. Unit tests to excersise a
simple hash table usage and catch the corruption were added.
To trash your environment, simply run this loop:
setenv i 0
while true; do
setenv v_$i $i
setenv v_$i
setexpr i $i + 1
done
