Re: Bug Report: Interactive Mode Glitches

[Nir Friedman <quicknir@xxxxxxxxx>]

Hi Daniel,

My apologies, I only realized upon rereading this that I completely omitted
a description of what happened! What happens is that it crashes the zsh
process. So if you are running zsh by simply calling it from bash, it
reverts to the bash process. If (more typically) you are running the zsh
process directly in your terminal emulator, it crashes that window of the
terminal emulator.

I'm running the latest zsh, 5.1.1, but I've been observing this bug since
5.0.7.

I have many things in my .zshrc, I am using prezto:
https://github.com/quicknir/prezto. However, I have duplicated the problem
in the past with a much more minimal setup, what I have below *should*
suffice. The problem is that I don't have a list of steps to reliably
duplicate it. Just use it for a while, keep typing and hitting backspace,
and at some point it goes off.

By interactive mode, I mean interactive menu completion mode in zsh. In
this mode after you hit tab (however many times), you will have a list of
possible completions that will automatically narrow as you type. It's
activated by this:

zstyle ':completion:*' menu select=0 interactive

I'm not sure if zsh is killed by signal or some other mechanism.

Cheers,

Nir
