There is no coredump, otherwise it would have read
Segmentation fault (core dumped)

Make sure you have your system configured to allow core dumps. Usually
this is done by saying

	ulimit -c unlimited

in your /etc/profile or other equivalent shell initializer. You can also
type it on the prompt before you run nagios' init-script.

Usually just 'core', although it could be 'core.<pid>' where <pid> is the
process id of the process that caused the coredump.

Use gdb.
$ gdb /path/to/nagios core
gdb> bt

Send the output of the "bt" command from gdb to
nagios-devel at lists.sourceforge.net along with nagios and ndoutils version
info and someone will look into it. You'll have to subscribe to nagis-devel
before you can post there. If you don't wish to do so, send your email here
and I'll make sure it reaches the right people.
