Looking at the libx11-dev package source code I see that the 'Display'
value is optimized out into a register variable, which is a pain since
that is likely key to the bug and doesn't show up in gdb output.
libx11/src/DefCursor.c:
int
XDefineCursor (
register Display *dpy,
Window w,
Cursor cursor)
{
This function is called from
gtk+2.0-2.16.1/gdk/x11/gdkwindow-x11.c::gdk_window_x11_set_cursor()
if (!GDK_WINDOW_DESTROYED (window))
{
XDefineCursor (GDK_WINDOW_XDISPLAY (window),
GDK_WINDOW_XID (window),
xcursor);
if (cursor)
impl->cursor = gdk_cursor_ref (cursor);
}
Which comes from:
#define GDK_WINDOW_XDISPLAY(win) (GDK_SCREEN_X11 (GDK_WINDOW_SCREEN
(win))->xdisplay)
#define GDK_SCREEN_X11(object) (G_TYPE_CHECK_INSTANCE_CAST
((object), GDK_TYPE_SCREEN_X11, GdkScreenX11))
#define GDK_WINDOW_SCREEN(win) (GDK_DRAWABLE_IMPL_X11
(((GdkWindowObject)
win)->impl)->screen)
