Description:
When a node starts, it will copy data from peer-node,
during this copy, a variable was left uninitalized,
which could if the starting node died during the code
lead to cluster crash when the node was later restarted.

How to repeat:
for i in `seq 100`; do testNodeRestart -l 10 -n Bug15587 T1 || break; done

Suggested fix:
Init variable

Documented bugfix in the NDB-6.2.19, 6.3.26, and 7.0.8 changelogs, as follows:

        A variable was left uninitialized while a data node copied data
        from its peers as part of its startup routine; if the starting
        node died during this phase, this could lead a crash of the
        cluster when the node was later restarted.

Closed.
