=begin
Ruby core-dumps when 'CTRL-C' is entered in irb. I only see
this behavior with zsh. Bash appears to do ok.

I'm not sure if this is a Ruby or a zsh issue. I'll be happy
to provide more information.

spitfire% which zsh
/usr/local/bin/zsh

spitfire% which zsh --version
zsh 4.3.9 (i386-portbld-freebsd6.3)

spitfire% echo $SHELL
/usr/local/bin/zsh

spitfire% ./irb19

This also reproduce on ruby 1.9.2dev (2009-07-14 trunk 24106) [x86_64-freebsd7.2].
So this seems FreeBSD's problem.

When you install Readline 6.0 from ports, it doesn't SEGV. But it ignores ^C.
