Below is a very short X Toolkit based program.  It just creats a widget,
realizes it, and then exits.  Pretty complex, eh?  The only problem is
that when I compile and run it on my machine, I get an error from
XtDestroyApplicationContext.

Has anyone else out there seen this behaviour?  Does the same thing
happen for you?
