Description: CREATE TABLE t1 (f_int1 INTEGER,f_int2 INTEGER , UNIQUE INDEX(f_int1)) PARTITION BY RANGE(f_int1 DIV 2) SUBPARTITION BY HASH(f_int1) SUBPARTITIONS 2 (PARTITION partb VALUES LESS THAN (2), PARTITION parte VALUES LESS THAN (4), PARTITION partf VALUES LESS THAN (10000)); SELECT * FROM t1 WHERE f_int1 = 10; ERROR HY000: Lost connection to MySQL server during query This bug seems to have a different reason than #16901, because a single column UNIQUE INDEX is sufficient for the crash. Experiments show, that the crash disappears when - the final SELECT "goes" not into the last partition - BY RANGE(f_int1 DIV 2) is repleced with BY RANGE(f_int1) - the subpartitioning is not used My environment: - Intel PC with Linux(SuSE 9.3) - MySQL compiled from source Version 5.1 last ChangeSet@1.2087.1.1, 2006-01-30 How to repeat: Please execute the statements above or use my attached testscript ml018.test copy it to mysql-test/t echo "Dummy" > r/ml018.result # Produce a dummy file with # expected results ./mysql-test-run ml018
