Subject: Core dump on completion after `for'
Date: Wed, 06 Mar 2002 19:19:36 +0000 [thread overview]
Message-ID: <7819.1015442376@csr.com> (raw)
% ./zsh -f
% for f in <TAB>zsh: segmentation fault (core dumped) ./zsh -f
It's at the first sprintf in the following in get_comp_string(). tok is
51, which is FOR, which is out of range for tokstrings, which only
handles tokens looking like punctuation.
if (inredir) {
rdstr = rdstrbuf;
if (tokfd >= 0)
sprintf(rdop, "%d%s", tokfd, tokstrings[tok]);
else
strcpy(rdop, tokstrings[tok]);
strcpy(rdstr, rdop);
}
We've got to this branch because redir is set for special commands which
take lists in ctxtlex():
if (IS_REDIROP(tok) || tok == FOR || tok == FOREACH || tok == SELECT) {
inredir = 1;
...
so there are two ways to handle it: make these three tokens special
cases of redirections, or simply ignore the inredir flag for them.
