+
+2007-04-16 John Darrington <john@darrington.wattle.id.au>
+
+ * t-test.q: Changed the output width of reported counts and
+ degrees of freedom, to avoid truncating these values. Thanks
+ to Seth Woolley for reporting this problem. A proper fix involves
+ re-thinking the output driver.

+
+Mon Jan 15 11:03:20 2007 Ben Pfaff <blp@gnu.org>
+
+ 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.

+ data put into hash.
+
