Testcase
DROP DATABASE test;CREATE DATABASE test;USE test;
CREATE TABLE child(a1 INT KEY,a2 INT)ENGINE=InnoDB;
SET @@session.foreign_key_checks=DEFAULT;
set global innodb_trx_rseg_n_slots_debug=1;
CREATE TABLE t2(c1 CHAR (1));#
CREATE TABLE t1(c1 TIME,c2 BINARY(1),c3 INT(1),c4 BINARY(1) KEY,c5 TIME UNIQUE KEY,c6 DEC(0,0) DEFAULT 3.141592);
ALTER TABLE child ADD CONSTRAINT fk_4 FOREIGN KEY(a1,a2)REFERENCES parent(a,b) ON DELETE CASCADE ON UPDATE CASCADE,ALGORITHM=INPLACE;
The attached tarball (1452772996_bug_bundle.tar.gz) gives the testcase as an exact match of our system, including some handy utilities
$ vi 1452772996_mybase # STEP1: Update the base path in this file (usually the only change required!). If you use a non-binary distribution, please update SOURCE_DIR location also
$ ./1452772996_init # STEP2: Initializes the data dir
$ ./1452772996_start # STEP3: Starts mysqld
$ ./1452772996_cl # STEP4: To check mysqld is up
$ ./1452772996_run_pquery # STEP5: Run the testcase with the pquery binary
$ ./1452772996_run # OPTIONAL: Run the testcase with the mysql CLI (may not reproduce the issue, as the pquery binary was used for the original testcase reduction)
$ vi /dev/shm/1452772996/error.log.out # STEP6: Verify the error log
$ ./1452772996_gdb # OPTIONAL: Brings you to a gdb prompt with gdb attached to the used mysqld and attached to the generated core
$ ./1452772996_parse_core # STEP7: Creates 1452772996_STD.gdb and 1452772996_FULL.gdb; standard and full variables gdb stack traces
