Hello, I've successfully installed Roundcube 0.4.2 on Solaris 10. I'm running : Apache 2.2.11 PHP 5.2.14 Mysql Ver 14.14 Distrib 5.1.30 On the same server I'm running Squirremail. But when I tried to login from the Roundcube start page, Apache crashed:

It looks like it crashes on iconv (in include/main.inc: "iconv('', $iconv_options, '')"). So, try to reinstall iconv/php. Finally you can disable iconv extension in php.ini, in this case Roundcube will use mbstring extension or other build-in methods.
Hello Alec,
thank you for your answer. You are right the iconv is not working correctly and crashed my Apache
I tried to run the simple following PHP code which create a core dump.
www-n2:root>vi iconv.php
<?php $text = "abcde"; echo iconv('UTF-8', 'ISO-8859-1', $text), PHP_EOL; ?>
I'll reinstall the iconv/PHP as you recommended.
thanks again.

Hello Alec,
I've reinstalled the iconv , I've compiled iconv from GNU. but the PHP still crashed and create a core dump. after simple PHP script.
In my php.ini I have no extension=iconv.so I just have [iconv]
;xxx ;xxx
so all iconv commented
so, how to disable the iconv support in PHP ? AFAIK, iconv is compiled by default in PHP.
May be I should send my question to PHP users, it seems, this is not a Roundcube issue but PHP issue. Anyway, thank you for your help.
Dancer.

What exactly did you recompile? This is a function in PHP (php_iconv_string) calling the iconv function in your C library, where the thread is actually dying. This looks like it's between between PHP and your C library.
If we google "php_iconv_string", the very first hit is this:
http://bugs.php.net/bug.php?id=53005 ("iconv() fails in ext/iconv/iconv.c php_iconv_string").
Hey look, it's a PHP bug in the CLOSED state, about the same crash that you are having.
And, oh look, it's logged agains the Solaris 10 platform.
What are the odds that it's the same?
The guy who submitted the bug (php at jrdtech dot com) seems to have also found the solution. See his follow-up comment at the bottom:
"needed to do preload, runs great"

Hello,
What exactly did you recompile?
I've recompiled the libiconv in my Solaris, i.e I've replaced the libiconv from Sunfreeware by the one from GNU. I've read the PHP bug submitted by (php at jrdtech dot com) and will try to get the solution he has found("needed to do preload") thanks.

You could try to disable just 'iconv' function using disable_functions option in php.ini.
Hello Alec, I have disabled the iconv using disable_functions in php.ini as you recommended, Roundcube is now working!! Thank you very much for your help.
My next step is to fix this iconv issue in my PHP, since the other site I'm running may use the iconv function. It seems this is a bug (iconv/PHP), described in PHP.net.
regards,
D.
