I've recompiled xemacs21 packages with debugging, and I've installed the
libx11 debug packages. Here's the new backtrace:

XFontsOfFontSet is in libx11-6. The nearest XEmacs code is #6, this
function:
static Widget
xlw_create_menubar (widget_instance* instance)
{
Arg al [1];
Widget widget;
XtSetArg (al [0], XtNmenu, instance->info->val);
widget = XtCreateWidget (instance->info->name, xlwMenuWidgetClass,
instance->parent, al, 1);
XtAddCallback (widget, XtNopen, pre_hook, (XtPointer)instance);
XtAddCallback (widget, XtNselect, pick_hook, (XtPointer)instance);
return widget;
}
The line that crashes is "widget = XtCreateWidget..." Here's what's
inside "instance":
(gdb) p instance->info
$1 = (struct _widget_info *) 0x8582fd0
(gdb) p instance->info->name
$2 = 0x8579258 "menubar"
(gdb) p instance->parent
$3 = (Widget) 0x8567218
(gdb) p *instance->parent
$4 = {core = {self = 0x8567218, widget_class = 0x822f740, parent =
0x8566f90,
xrm_name = 2978, being_destroyed = 0 '\0', destroy_callbacks = 0x0,
constraints = 0x0, x = 0, y = 0, width = 0, height = 0, border_width
= 1,
managed = 0 '\0', sensitive = 1 '\001', ancestor_sensitive = 1 '\001',
event_table = 0x0, tm = {translations = 0x0, proc_table = 0x0,
current_state = 0x0, lastEventTime = 0}, accelerators = 0x0,
border_pixel = 0, border_pixmap = 2, popup_list = 0x0, num_popups = 0,
name = 0x852779b "container", screen = 0x83fb140, colormap = 32,
window = 0, depth = 24, background_pixel = 16777215,
background_pixmap = 2, visible = 1 '\001', mapped_when_managed = 1
'\001'}}
(gdb) p *instance
$5 = {widget = 0x0, parent = 0x8567218, pop_up_p = 0 '\0', info =
0x8582fd0,
next = 0x0}
(gdb) p al[0]
$6 = {{name = 0x820c96a "menu", value = 139956840}}
(gdb) p al[1]
$7 = {name = 0x8579250 ".xpm\021", value = 140085040}
It'd be nice if someone could comment on whether this bug is probably
XEmacs or libx11 (or libxt).
Thanks,
