Well this is a goofy one.  The following doesn't work:
(X11R3 no less; and with a List widget)

	Arg arg;

	XtSetArg(arg, XtNcallback, callrec);
	XtSetValues(widget, arg, ONE);

Seems to segviol down in XtSetValues.  The work around is:

	Arg arg[1];

	XtSetArg(arg[0], XtNcallback, callrec);
	XtSetValues(widget, arg, ONE);

Some artifact of the XtSetArg macro no doubt.  Yuck.
(I'm Mailing to xbugs too)
