Re: Bug report: segfault when pasting (function and alias names collide)

[Victor Volle <victor.volle@xxxxxxxxxxxxxxxxx>]

I tried to reduce it as far as possible, but it does not happen without
oh-my-zsh.
This is the minimal version that still shows the segfault:

    source $ZSH/oh-my-zsh.sh

    alias h='history'

    h() {
      echo "foo"
    }

Steps to reproduce:

   0) install latest oh-my-zsh
   1) Invoke `zsh -f`
   2) source the above script
   3) paste anything
