is not a core dump

Here's what I tried to figure this out: 

$ ddd --help
GNU DDD 3.3.12-test6cvs (i686-suse-linux)
....

Usage:

    ddd [options...] executable-file [core-file | process-id]
                                      ^^^^^^^^^


I'd take that error message at face value -- ddd thinks test3.tcl is not
a core dump. Core dumps on my system usually start core or have the
extension core. What does the "file" command think of test3.tcl?

Perhaps you meant to drop off "ns"?
