OK, so what does this print:

 (gdb) frame 10
 (gdb) p *glyph

also these:

 (gdb) p *width
 (gdb) p w->contents
 (gdb) xtype

If the last command says it's a buffer, type "xbuffer", otherwise type
"xwindow" and show the result.

Btw, how come the call to get_window_cursor_type is shown with its
argument in reverse order?  In the backtrace:

  #10 0x00000004000469f9 in get_window_cursor_type (active_cursor=<synthetic 
pointer>, width=0xbfd6ac, glyph=0x10c46fd0, w=0x12af8400) at xdisp.c:28096

when the actual function argument list is this:

  get_window_cursor_type (struct window *w, struct glyph *glyph, int *width,
                          bool *active_cursor)

What does this print:

 (gdb) ptype get_window_cursor_type

Something really weird went on in that frame #10...
