It gives a hint. Can you type "bt" before you type "n" here:
> 11985 if (FRAME_ICONIFIED_P (f))
> (gdb) n
and show the resulting backtrace? Also, type "bt" _after_ you type
"n" there and see this line:
> Ffuncall (nargs=1, args=args@entry=0x7fffffffd258) at eval.c:3048
> 3048 lisp_eval_depth--;
You see, FRAME_ICONIFIED_P doesn't call Ffuncall, and there's no such
call anywhere in sight inside x_iconify_frame. So either the macro
FRAME_ICONIFIED_P somehow signaled an error (which I don't think can
happen), or something else kicked us out of the function when we tried
to see if the frame is already iconified. The question is: what did
kick us out and why?
