Not likely since nctest has been used quite a bit on many different
systems.

I suggest recompiling with symbolic debugging enabled.  Set the
environment variable CFLAGS to `-g' and re-execute the configure script,
e.g.

    setenv CFLAGS -g
    ./configure >&! configure.log

Then, execute a `make'.  Then, drop into the nctest/ subdirectory and
execute a `make test'.  You should wind up with a `core' file if the
utility terminates abnormally.  You should then be able to examine the
contents of the core file using a symbolic debugger (e.g. dbx(1)).
