zsh dies (3.1.5-pws-16)

[Tatsuo Furukawa <frkwtto@xxxxxxxxxxxxxxx>]

Hello, zsh developers.  I found another bug.


1. Start new zsh

    $ zsh

2. Check that COLUMNS environment variable is defined.

    $ env | grep COLUMNS   
    COLUMNS=80

3. Remove COLUMNS

    $ unset COLUMNS

4. Execute "env" command.

    $ env

5. zsh dies. (ToT)

    zsh: segmentation fault  zsh


I tested the following situation:

Dies:
    zsh:    3.1.5-pws-16
    OS:     Linux/Slackware 3.1

OK:
    zsh:    3.0.6-pre-2
    OS:     Linux/Slackware 3.1


I didn't make patch to fix this problem.  Because, Bart Schaefer said
that zsh 3.1.X's resize code is older than 3.0.X's (NOTE 1).  And,
3.0.6-pre-2 does not have the problem.  So, I think 3.1.X's resize
code should be changed into 3.0.X's.  (I can help to making patch!)
