Description:
==32193== Conditional jump or move depends on uninitialised value(s)
==32193==    at 0x820CF6B: Configuration::fetch_configuration() (Configuration.cpp:239)
==32193==    by 0x809A87F: main (main.cpp:74)

How to repeat:
Run ndbd :)

Suggested fix:
ndb/src/kernel/vm/Configuration.cpp
in constructor:
Configuration::Configuration()
{
  _programName = 0;
  _connectString = 0;
  _fsPath = 0;
  _backupPath = 0;
  _initialStart = false;
  _daemonMode = false;
  m_config_retriever= 0;
}

add cleanup of m_clusterConfig

Configuration::Configuration()
{
  _programName = 0;
  _connectString = 0;
  _fsPath = 0;
  _backupPath = 0;
  _initialStart = false;
  _daemonMode = false;
  m_config_retriever= 0;
  m_clusterConfig = 0;
}
