This gave an error for me, I tried the following commands.

  (gdb) p XFRAME (selected_frame)
  No symbol "XFRAME" in current context.
  (gdb) p xframe (selected_frame)
  No symbol "xframe" in current context.

But xframe (selected_frame) worked.

  (gdb) p selected_frame
  $1 = XIL(0x1e81975)
  (gdb) xtype
  Lisp_Vectorlike
  PVEC_FRAME
  (gdb) xframe (selected_frame)
  $2 = (struct frame *) 0x1e81970
  "emacs <at> toolbox"
  (gdb) p *$

Attaching the output as a file. This is the only frame in that Emacs
instance and it's frozen. I'm keeping gdb and Emacs running in case if
we need it.
