How to repeat:
DROP DATABASE test;CREATE DATABASE test;USE test;
create TABLE t1(a datetime not null) engine=csv;
delete from t1 where a = 0;
LOCK TABLES t1 LOW_PRIORITY WRITE;
INSERT INTO t1  VALUES ('10:10:10.993');
REPAIR TABLE t1 EXTENDED;

To reproducing the bug we need to use multi thread pquery binary, the
attached tarball gives the testcase as an exact match of our system,
including some handy utilities
$ vi {epoch}_mybase # Update base path in this file (the only change
required!)
$ ./{epoch}_init # Initializes the data dir
$ ./{epoch}_start # Starts mysqld
$ ./{epoch}_cl # To check mysqld is up
$ ./{epoch}_run_pquery # Run the testcase with pquery binary(produces
output)
$ vi /dev/shm/{epoch}/error.log.out # Verify the error log
$ ./{epoch}_gdb # Brings you to a gdb prompt attached to correct
mysqld
& generated core
$ ./{epoch}_parse_core # Create {epoch}_STD.gdb and {epoch}_FULL.gdb;
standard and full var gdb stack traces
etc.
