+       * regression.q: Fixed p-value computation in the test for
+       individual regression coefficients.

+
+       Fix bugs found by valgrind when --enable-debug is used with the
+       new case code.  These bugs are hidden when the data set is small
+       enough to find in memory; if a bigger data set that would overflow
+       to disk were used, then data corruption would occur.
+
+       * chisquare.c (create_freq_hash): Pass free_freq_mutable_hash to
+       hsh_create as free function.  Make copy of data put into hash.
+
+       * oneway.q (free_value): New function.
+       (run_oneway): Use free_value as arg to hsh_create.  Make copy of
+       data put into hash.
+
+       * rank.q (rank_cases): Don't access data in case after we've given
+       away the case.
