bindkey induced coredump

[Mark Hanson <mark@acucobol.com>]

$ zsh -f
$ echo $ZSH_VERSION
3.0.0
$ bindkey -v
$ bindkey -r '\e[A'
$ bindkey -r '\e[B'
$ bindkey -r '\e[C'
$ bindkey -r '\e[D'

coredump

Here's a stacktrace:

I put the "bindkey -r"'s in there to keep zsh from waiting to see if it
had an escape key or not.  The lag throws me off, but if there aren't
any other keys bound to an escape sequence, the lag goes away.  If you
need more information, let me know.

Thanks,
Mark
