Hi Markus i just saw this change which copies the user string a temporary buffer only to \0 terminate it before printf
http://www.squid-cache.org/Versions/v3/3.0/changesets/b9061.patch While entirely fine it's a little more complex than it need to be. Instead of copying the unterminated string you can apply a size limit to the output. Size limit for %s is in the precision field and causes at most that many characters to be copied to the output. When combined with the * size specifier one can easily print sized strings without the need for \0 termination. printf("%.*s\n", token.length, token.data); Regards Henrik
