#33268 [NEW]: iconv_strlen works only with a parameter of < 3 in length

From: markus dot lervik at necora dot fi Operating system: SuSE Linux 9.2 PHP version: 5.0.3 PHP Bug Type: ICONV related 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.
