zsh-3.1.x cdmatch problem

zsh-3.1.x cdmatch problem

[Paul Lew]

I am trying switch from 3.0.x to 3.1.x but one problem is really
bugged me: The completion after 'cd' command generated:

    zsh: bad math expression: unbalanced stack

This does not happen for 3.0.x, the function cdmatch is the one from
standard distribution:

(3)ezdzit lew Src>>> function cdmatch {
emulate -R zsh
setopt localoptions
local narg pref cdp
read -nc narg
read -Ac pref
cdp=(. $cdpath)
reply=(${^cdp}/${pref[$narg]%$2}*$2(-/DN^M:t))
return
}

If I get rid of the reply= line, the error message disappeared but
there is also no reply list for the completion.

Any idea what wrong here?  Thanks in advance.

The cdmatch function you quoted is not the one from the standard 3.1.[45]
distribution, but in any case I don't see this error for any completion
that I attempted (even after I fixed cdmatch2, see my other posting).

It would help if you told us:

(1) Exactly what `x' you mean when you say 3.1.x;
(2) A specific example completion that produces this result.

This is the result of entering 'functions cdmatch', the comments were
removed.  The date of the file from zsh-3.1.5/Functions is:

(3)ezdzit lew Src>>> ls -l cdmatch
-rwxr-xr-x   1 lew      users        709 May 11  1997 cdmatch

(3)ezdzit lew Src>>> sum cdmatch
58242      1 cdmatch

Seems this file has not changed since May 11 1977.  Could you tell me
what you get when you enter 'functions cdmatch'?

Make it simple, 3.1.5 (with no patch applied).

$ tar xf zsh-3.1.5.tar.gz
$ cd zsh-3.1.5/Src
$ cd <TAB>

My cdpath value is: (. .. /usr/users/lew), unsetting it make no
difference.
