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-mcrypt \
--with-mysql=mysqlnd \
--with-openssl=/opt/local \
--with-iconv \
--without-pdo-sqlite \
--without-sqlite \
--without-sqlite3 \
--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 ~]#
