Description:
This one is a little strange in the fact that you have to run the 2 test before rename.test in order to get the core to happen. I have been unable to break it down and further then that at this point.
rename [ fail ]

How to repeat:
I can repeat the core each time by using
./mysql-test-run --force --mysqld=--default-storage-engine=ndb --with-ndbcluster-all --ndb-extra-test --do-test=r
The test will run:
range
read_only
rename - this is where the core is at.
