Subject: PHP5.4: PHP-FPM + Gettext == invalid pointer
From: svanpoeck@gmail.com (Steven VAN POECK)

Hi,

Whenever I activate the gettext extension, PHP-FPM dumps a heap upon 
starting (see output below)

Although the output finishes with "Aborted. Failed", the php processes 
are working ok, gettext too.

PHP 5.4 was compiled with these options:
./configure --sysconfdir=/etc/php5 --with-config-file-path=/etc/php5 
--with-config-file-scan-dir=/etc/php5/conf.d --enable-fpm 
--with-fpm-user=www-data --with-fpm-group=www-data --with-openssl 
--with-zlib=shared --enable-bcmath --with-curl=shared --with-gd=shared 
--with-gettext=shared --enable-intl --enable-mbstring 
--with-mcrypt=shared --enable-pcntl --disable-pdo --with-mysqli=mysqlnd 
--disable-posix --with-libedit=shared --with-readline=shared 
--with-recode=shared --enable-sockets --with-tidy=shared 
--with-xsl=shared --enable-zip --with-pear --with-gmp=shared

If I deactivate the gettext extension, PHP-FPM systematically segfaults 
upon startup but still runs fine:
root@some-vm:~# /etc/init.d/php-fpm restart
Gracefully shutting down php-fpm . done
Starting php-fpm Segmentation fault
  failed

The app is running on an nginx 0.7.67

Just wanted to know if this is normal behaviour and if not, should I 
file a bug ?

Thanks,
Steven
