Have you tried a search on metalink for 8.1.6.3 and ORA-00600 in the Advanced search section of the Bug database ?
Offhand, this might work: create a table with 3 columns create table t1 as select trunc((rownum-1)/100,0) b1, mod(rownum,100) b2, rpad(rownum,100) v1 from all_objects where rownum <= 2000 ; Create a two column bitmap index create bitmap index t1_bx on t1(b1,b2) Select on b1 with an equality and b2 with a range scan. select * from t1 where b1 = 10 and b2 between 40 and 80 ; I think this one breaks an 8.1.6 database.
