Description:
It seems that it is not a specific mis-configuration that cause the core file. Below are three different examples all caused core files.

core files will be saved to ndb08:/space/bug#### where #### == the number of this report.

How to repeat:
mis-configure the config.ini and start ndb_mgmd process

Suggested fix:
ndb_mgmd should handle the bad configuration w/o producing a core file.
