[zsh 4.0.1-pre-2 bug] named directories disappear

[zsh 4.0.1-pre-2 bug] named directories disappear

[Vincent Lefevre]

I use zsh 4.0.1-pre-2 on

Linux greux.loria.fr 2.2.17 #13 SMP Tue Dec 12 15:26:51 MET 2000 i686 unknown

The named directory ~out was defined, but it has disappeared:

greux:~> echo ~out                                                    <16:41:04
zsh: no such user or named directory: out

This bug occurred with a previous version several weeks or months ago.

} zsh: no such user or named directory: out

    bug () {
        hash -d out=$HOME
        echo ~out
        local out
        out=(oops) 
        ( echo ~out )
	: Without the subshell above, this line is never reached
    }

The local variable "out" is used by _pids, so that named directory will be
stomped whenever you complete process IDs.

On the other hand, if you actually set the global variable "out":

    unbug () {
	out=$HOME
	bug
	echo ~out
    }

The named directory still gets stomped, but is automatically restored any
time you refer to it.

Yes, this was probably the problem (I remember I completed process IDs).

But I use hash -d out=... from my .zshenv so that I can use it anywhere,
and in particular in an interactive shell. So, what can I do?

Until the bug gets fixed, replace the `hash -d' with:

    out=...
    : ~out

As long as you don't use $out for anything else, this should work fine.
