I just start it and immediately press Ctrl-C as soon as I see the
prompt. In fact, if it is actually running any kind of loop, it just
enters the debugger and then hangs when I tell it to :continue.

It also crashes if I enter (read) and then press Ctrl-C.

If ecl-readline is used, it does not crash even while doing (read).

P.S. This is the beginning of the recursion:
