It has never been documented that you could (or should) call
NdbOperation::getValue() on a BLOB column.  But, in the past, it was 
allowed, and you could do simple things like call NdbRecAttr::isNULL()
on the NdbRecAttr that it returned. 

In Cluster 7.0 this results in an abort() inside the NDB API. 

1. Edit the Makefile -- look at MYSQL_ROOT6 and MYSQL_ROOT7

2. Create the "typ8" table:  mysql -u root < typ8.sql 

3. Type "make" -- if you have both Cluster 6.3 and Cluster 7.0 present 
this will build two versions of the test program 

4. The executables, "blob-bug-ndb-6" and "blog-bug-ndb-7", take
one (optional) argument -- the NDB Connect String.

5. If you run the blob-bug-ndb-7 executable and then choose the 
"bug" option, the program will crash.
