Details:

default branch, hg id 80906ac05e7d

with empty history (rm ~/.octave_hist) start CLI with

./run-octave --no-gui


then press CTTRL+C, then cursor up (which should give the last line of
history) results sometimes in a segfault, sometimes it shows


symbol lookup error: /lib/x86_64-linux-gnu/libreadline.so.5: undefined symbol:
history_list


I tried to debug this with getpid and attaching gdb but as soon as there is a
command executed (getpid in this case) it doesn't crash.
