Bug description: iconv_strlen works only with a parameter of < 3 in length
Description:
------------
iconv_strlen seems to have a peculiar bug. It doesn't work when the string
searched is less than three characters long (or an empty string), but
reports
Notice: iconv_strlen() [function.iconv-strlen]: Unknown error (2) in
/usr/local/apache/htdocs/test2.php on line 7
This is tested on PHP 5.0.3 and 5.1 from CVS (2005-06-07), tested with the
built-in (glibc 2.3.3) iconv and libiconv 1.9.2 from gnu.org.
This problem doesn't seem to surface on my Debian 3.1 development server,
but I get it on my SuSE 9.2 desktop.
I have tried to set the encodings with iconv_set_encoding() and I have
tried to set the encoding as a parameter to iconv_strlen(), both produce
the same error.
The other iconv-functions (iconv_strpos, iconv_substr, iconv_strrpos) work
fine.
Since the iconv-functions do not seem to work from the commandline
(produces an Unknown error(29)), I cannot get a proper strace (strace
seems to say that iconv is trying to seek on /dev/pts/5, which apparently
is impossible). It doesn't crash apache either, so I'm not sure where I'd
grab the backtrace.
