Description:
The MySQL Cluster data node(ndbd) installs a function pointer in the 'ndb_new_handler' global variable on startup. The purpose of this is to shutdown the ndbd if failure to allocate more memory with new occurs.

Since the code that is supposed to call the 'ndb_new_handler' function  pointer has been disabled (with #if 0) wince a long time, this functionality does not work anymore.

How to repeat:
MCI

Suggested fix:
Use the  C++ 'set_new_handler' function.
