Description:
After a restore using disable-indexes then rebuild-indexes a table operation crashes ndbd with:

Message: Assertion (Internal error, programming error or missing error message, please report a bug)
Error: 2301
Error data: ArrayPool<T>::getPtr
Error object: ../../../../../storage/ndb/src/kernel/vm/ArrayPool.hpp line: 451 (block: DBDICT)
Program: /home/linuxjedi/Programming/Builds/mysql-cluster-com-7.0.11a/libexec/ndbd

Subsequent starts crash with:

Message: Internal program error (failed ndbrequire) (Internal error, programming error or missing error message, please report a bug)
Error: 2341
Error data: dbdict/Dbdict.cpp
Error object: DBDICT (Line: 17657) 0x0000000a

How to repeat:
1. Create table with unique
2. insert a few rows
3. ndb_mgm> start backup
4. shell> ndb_restore --backupid=1 --nodeid=2 --parallelism=64 --skip-table-check --exclude-table=mysql.ndb_replication --disable-indexes --restore_data
5. shell> ndb_restore --backupid=2 --nodeid=2 --parallelism=64 --skip-table-check --exclude-table=mysql.ndb_replication --rebuild-indexes
6. drop table the table in mysql

Node failure at step 6

it feels like this is very very unlikely to occur.

I think it therefor should be a P3
