The part with function and alias has not been "fixed" because it's not
a bug.  To define a function without interpreting aliases in the
function name, use this syntax:

    function f {
      ⋮
    }

All segfaults are bug, but how do you reproduce this one?  I did:

$ zsh -f
% history() {
  ⋮ copied the function body from your mail
  }
% <paste>

and it did not segfault.  Can you provide a minimal reproduction script
starting from `zsh -f`?  (and without third party modules, if at all
possible)

Thanks,
