Yes, Emacs is looping infinitely. It is spinning busily inside
command_loop_2 which calls internal_condition_case which calls
command_loop_1 which calls read_key_sequence. Somewhere down in
read_key_sequence is thrown an exception. The longjump lands back in
setjmp in the internal_condition_case which returns to
command_loop_2. This repeats forever.
I tried to find what exception it is and from where in the downstream
of read_key_sequence it is thrown, then I ran out of my time for now.
I'll continue the pursuit later.
