Description:
------------
After successfully compiling PHP 5.3.6 on (patched) Solaris 10 with all required GNU packages from sunfreeware.com, iconv_strlen($var) causes Apache2 extension to crash. Only error apache shows is [notice] child pid 34232 exit signal Segmentation fault (11). No output to browser was generated.

configure command for compiling PHP was:

./configure --verbose --with-gnu-ld --prefix=/usr/local/php --without-gd --disable-pdo --without-pdo-sqlite --without-sqlite --with-config-file-path=/usr/local/php/lib --with-oci8=/export/home/oracle/product/11.1.0/pweb --with-apxs2=/usr/local/apache2/bin/apxs --enable-bcmath --with-openssl=/usr/local/ssl --with-ldap=/usr/local --with-bz2 --enable-calendar --enable-ctype --with-curl=/usr/local/curl --with-curlwrappers  --enable-exif --enable-ftp --with-zlib=/usr/local --with-gettext --with-gmp --enable-hash --enable-json --enable-mbstring --enable-mbregex --enable-pcntl --with-libedit=no --with-readline --enable-session --enable-shmop --enable-simplexml --enable-soap --enable-sockets --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-tokenizer --enable-wddx --with-libexpat-dir=/usr/local --enable-xml --enable-xmlreader --with-xmlrpc --enable-xmlwriter --with-xsl --enable-zip --disable-static --enable-pcntl --enable-magic-quotes --with-pcre-dir=/usr/local --with-pcre-regex --with-pear


Test script:
---------------
print iconv_strlen("test","UTF-8");

Expected result:
----------------
generate some output

Actual result:
--------------
apache thread killed, error [notice] child pid 34232 exit signal Segmentation fault (11) in errorlog and no output for browser.

Ah this is so stupid, I was missing the pkg://solaris/system/library/iconv/unicode-core package...

To check if you're missing it too (only works on Solaris 11.1):

$ iconv -l
Failed to open the directory /usr/lib/iconv/geniconvtbl/binarytables/.

When you get that, you need to install the unicode-core pkg and everything (including php's iconv_strlen) will be fine after that.
