What should I look for when that happens?
next_frame has that loop "while (passed < 2)" where emacs gets stuck,
but prev_frame does not. Any idea what can it make it get stuck there?
Hm... strange values (dead frame?) in Vframe_list may be a reason.
Next time when it's get stuck, attach gdb and examine:
1) `frame' arg of next_frame;
2) each entry in Vframe_list, like this:
(gdb) call debug_print (Vframe_list)
(#<frame emacs@localhost 0x102d390>)
(gdb) p *(struct frame *)0x102d390

In particular, if you find the frame with zero f->terminal pointer,
we have dead frames in the game, which is definitely wrong.
