Doesn't produce any output after attaching GDB to the Emacs process
which consumes CPU? That's not possible. Please show all the
commands you did, starting from invoking Emacs that will later consume
CPU, including commands inside Emacs and outside it.
Note that the GDB you attach to Emacs should be a new GDB process, not
the one you ran inside Emacs.
