Bug description:PHP built from source on Solaris gets SIGSEGV with libiconv
Description:
------------
With PHP built from source on a Joyent SmartMachine and using the operating
system's libiconv, simple uses of the PHP iconv function result in
SIGSEGV.
PHP builds without (related) warnings and is linked to the libiconv shared
library:
[root@gnp2b7ak ~]# ldd $(which php) | grep iconv
libiconv.so.2 => /opt/local/lib/libiconv.so.2
[root@gnp2b7ak ~]#
We're using the following configuration:
./configure \
--disable-ctype \
--disable-dom \
--disable-fileinfo \
--disable-flatfile \
--disable-inifile \
--disable-ipv6 \
--disable-memcache-session \
--disable-phar \
--disable-posix \
--disable-session \
--disable-simplexml \
--disable-xmlwriter \
--enable-mbstring \
--enable-memcache \
--host=i386-sun-solaris2 \
--mandir=/opt/local/man \
--prefix=/opt/local \
--with-apxs2=/opt/local/apache2/bin/apxs \
--with-config-file-path=/opt/local/etc \
--with-curl \
--with-gd \
--with-jpeg-dir=/opt/local \
--with-libxml-dir=/opt/local \

--with-pdo-mysql=mysqlnd \
--with-pear \
--with-png-dir=/opt/local \
--with-regex=system \
--with-zlib \
--with-zlib-dir=/usr
Test script:
---------------
php -r 'echo iconv("UTF-8", "UTF-8", "Hello, world.\n");'
Expected result:
----------------
[root@gnp2b7ak ~]# php -r 'echo iconv("UTF-8", "UTF-8", "Hello,
world.\n");'
Hello, world.
[root@gnp2b7ak ~]#
Actual result:
--------------
[root@gnp2b7ak ~]# php -r 'echo iconv("UTF-8", "UTF-8", "Hello,
world.\n");'
Segmentation Fault (core dumped)
[root@gnp2b7ak ~]#
Note that the iconv(1) program works fine:
[root@gnp2b7ak ~]# echo "Hello, world." | /opt/local/bin/iconv -f UTF-8 -t
UTF-8
Hello, world.
[root@gnp2b7ak ~]#
