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


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 
but PHP issue.
Anyway, thank you for your help.

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.
