WL4086 modified the internals of scan and index scan so that they always use NdbRecord mechanisms internally.
NdbRecord mechanisms support the NdbInterpretedCode Api rather than the old interpreted program Api methods.
The NdbRecord checks in the old interpreted program Api methods were not being hit as they were placed too late in the decision path.
This resulted in corrupt signals beings sent to the kernel.

Documented in the 5.1.23-ndb-6.2.14 and 5.1.24-ndb-6.3.13 changelogs as follows:

        Using NDB API applications from older MySQL Cluster versions with 
        libndbclient from newer ones caused the cluster to fail.
