BUG#30324: Grouping queries with COUNT(DISTINCT bit column) return wrong results
- The bug was caused by COUNT(DISTINCT ...) code using Unique object in
a way that assumed that BIT(N) column occupies a contiguous space in
temp_table->record[0] buffer.
- The fix is to make COUNT(DISTINCT ...) code instruct create_tmp_table to
create temporary table with column of type BIGINT, not BIT(N).
