I can confirm that it happens without any readline-ish extensions (and in fact
no ~/.csirc at all). This chicken 4.7.0 is on FreeBSD/amd64 9.1-RELEASE.

It should be noted that ^\ sends SIGQUIT, similar to the way ^C sends SIGINT,
and in fact csi segfaults if I kill -QUIT it as well.


Best regards,
