Subject: PATCH: hist: remove wrong NULL terminator
Date: Fri, 9 Jan 2015 13:43:39 +0100 [thread overview]
Message-ID: <1420807419-9270-1-git-send-email-mikachu@gmail.com> (raw)
This actually writes a NULL to some arbitrary location in the caller function's stack. Found by Coverity (Issue 1255746).
The start of the quote() function does char **str = tr; and is called like this,
quote(&sline);
sline in turn is just a char *sline;
The result of str[1] = NULL; is then, as far as I can tell, not anything good. I also can't see any other thing that might have been intended to be NULL-terminated here, so just remove it.
