Yup, and the display variable has been set.

I have gone over all the stuff going on before the call to xvf_create_form
and I am reasonably sure that no array ends are being over written.

No calls to any xvdisplay routines yet.  Haven't gotten that far 8).


I've tracked down exactly where the error is occuring :

       glyph_button = XtCreateManagedWidget(label, commandWidgetClass,
                                             parent,arg,i);

This is line 795 in KHOROS_HOME/src/xvroutines/Lib/xvforms/wid_util.c.

The stack of calls looks like this :
xvf_form_create_glyph_sel
xvf_build_form
run_enterob
main

It looks as though the widget it is trying to create is the 'Glyph'
button at this point.

At the point of error the values of the arguments are :
label = 0xf46b8 "Glyph"
parent = 0x1326c8  (This is the form->back widget)
arg = (
{
        name  = 0xf4668 "width"
        value = 49
}
{
        name  = 0xf466e "height"
        value = 15
}
{
        name  = 0xf4675 "fromVert"
        value = 0
}
{
        name  = 0xf467e "fromHoriz"
        value = 0
}
{
        name  = 0xf4688 "horizDistance"
        value = 7
}
{
        name  = 0xf4696 "vertDistance"
        value = 7
}
{
        name  = 0xf46a3 "label"
        value = 1001144
}
{
        name  = 0xf46a9 "resizable"
        value = 1
}
{
        name  = 0xf46b3 "font"
        value = 1269496
}
`lxvobjects`xvf_mycreate_glyph_widget`i = 9 (9 args in arg)


And last but not least, the error was :
signal BUS (alignment error) in Get_GC at 0x60e64
Get_GC+0x14:    ld      [%o0 + 4], %o0


Any help is most appreciated.
