+
+	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.

+Tue Jan  9 19:16:11 2007  Ben Pfaff  <blp@gnu.org>
+
+	Fix bug #18739.
+	
+	* aggregate.c (parse_aggregate_functions) Initialize
+	function_name.

+
+	Simplify missing value handling.
+	
+	* aggregate.c (struct agr_var): Remove `bool include_missing', add
+	`enum mv_class exclude'.  Remove `int missing', add `bool
+	saw_missing'.  Update users.
+
+	* descriptives.c (struct dsc_trns): Removed `int
+	include_user_missing', add `enum mv_class exclude'.  Update users.
+	(struct dsc_proc): Ditto.
+
+	* examine.q: (static var value_is_missing): Rename
+	`exclude_values', change type to `enum mv_class'.  Update users.
+
+	* rank.q: Ditto.

+
+	* frequencies.q : Fixed bug #17420, where the table bounds were overun
+	when /FORMAT=nolabels was given.
