47 Mon Jan 15 11:03:20 2007 Ben Pfaff <blp@gnu.org>
49 Fix bugs found by valgrind when --enable-debug is used with the
50 new case code. These bugs are hidden when the data set is small
51 enough to find in memory; if a bigger data set that would overflow
52 to disk were used, then data corruption would occur.
54 * chisquare.c (create_freq_hash): Pass free_freq_mutable_hash to
55 hsh_create as free function. Make copy of data put into hash.
