seg fault with completion

seg fault with completion

[Oliver Kiddle]

This is in version 4.0.2 too so is not new.

s=( $a[(<tab> )
cursor positioned where I have put `<tab>'.

Now it's my turn to say "works for me" :-) (but in CVS version)

bor@itsrm2% s=($a[(TAB
Completing subscript flags
I -- highest index of value matched by subscript
...

It is not exactly your example, but then I get very strange result:

bor@itsrm2% s=( $a[(TAB )
bor@itsrm2% s=( $a[( )!
Completing parameter
!            #            $            ?            ARGC         BAUD
COLUMNS      EGID         ERRNO        EUID         GID          HISTSIZE
KEYTIMEOUT   LINENO       LINES        LISTMAX      LOGCHECK     MAILCHECK
OPTIND       PPID         RANDOM       SECONDS      SHLVL        TTYIDLE
UID          status

Hmm ...

Sorry, I forgot to mention this. Try again with setopt completeinword.
Should be repoducible - I've checked IRIX, Linux and Solaris and from
zsh -f.

Memory problem and hence not always reproducible.

It was using a pointer to compsuffix which might be freed by
ignore_suffix().

And that loop shouldn't be using `str' anyway, it's `more' there.

This'll go into 4.0.x, too.
