12 Fix bugs found by valgrind when --enable-debug is used with the
13 new case code. These bugs are hidden when the data set is small
14 enough to find in memory; if a bigger data set that would overflow
15 to disk were used, then data corruption would occur.

18 hsh_create as free function. Make copy of data put into hash.
