I posted an article earlier about problems with XtNbitmap but
got no response.
Here is another version of my program that doesn't work.
The error message and stack frames are also shown below.

I have no idea what's wrong with it.
Would someone please test run the program and see if it displays
the xlogo ?  If not?  Why not?

--------------------------------------------------------------------------------
#include <X11/Intrinsic.h>
#include <X11/Label.h>
#include <X11/bitmaps/xlogo16>

void main(argc, argv)
int  argc;
char **argv;
{
    Widget 	toplevel, xlogo;
    Arg 	args[10];

    toplevel = XtInitialize( NULL, "DEmo", NULL, 0, &argc, argv);

    xlogo = XtCreateManagedWidget("xlogo", labelWidgetClass, toplevel, NULL, 0);
    XtSetArg(args[0], XtNbitmap, XCreateBitmapFromData (XtDisplay(xlogo), 
	XtWindow(xlogo), xlogo16_bits, xlogo16_width, xlogo16_height)); 
    XtSetValues(xlogo, args, 1);

    XtRealizeWidget(toplevel);
    XtMainLoop();
}
