8 * regression.q (run_regression): Move casereader_destroy call so
9 that it always gets called, not just if there was some valid

15 * flip.c (struct flip_pgm): Remove `case_size' member (now
17 (cmd_flip): Pass var_cnt as number of cases instead of case_cnt,
18 to fix bug #20494. Don't assign to `case_size' member, which was
19 unused after assignment.

21 variables right, to fix bug #20493.

109 Fix bugs found by valgrind when --enable-debug is used with the
