This bug report has been into the 5.1.12 Changelog.
Description: The ha_innobase::index_prev() function is defined in sql/ha_innodb.cc at about 3427 line as { return(general_fetch(buf, ROW_SEL_PREV, 0)); } should be { statistic_increment(ha_read_prev_count, &LOCK_status); return(general_fetch(buf, ROW_SEL_PREV, 0)); } How to repeat: See description. Suggested fix: Add the line statistic_increment(ha_read_prev_count, &LOCK_status);
