Anonymous functions does not work: Function name must be a string

I have: 

PHP Version 5.4.20
'./configure' '--disable-fileinfo' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--enable-gd-native-ttf' '--enable-libxml' '--enable-mbstring' '--enable-pdo=shared' '--enable-soap' '--enable-sockets' '--enable-zip' '--prefix=/usr/local' '--with-apxs2=/usr/local/apache/bin/apxs' '--with-curl=/opt/curlssl/' '--with-freetype-dir=/usr' '--with-gd' '--with-imap=/opt/php_with_imap_client/' '--with-imap-ssl=/usr' '--with-jpeg-dir=/usr' '--with-kerberos' '--with-libdir=lib64' '--with-libxml-dir=/opt/xml2' '--with-libxml-dir=/opt/xml2/' '--with-mcrypt=/opt/libmcrypt/' '--with-mysql=/usr' '--with-mysql-sock=/var/lib/mysql/mysql.sock' '--with-openssl=/usr' '--with-openssl-dir=/usr' '--with-pcre-regex=/opt/pcre' '--with-pdo-mysql=shared' '--with-pdo-sqlite=shared' '--with-pic' '--with-png-dir=/usr' '--with-xpm-dir=/usr' '--with-zlib' '--with-zlib-dir=/usr'

And I test this code:

$greet = function($name) {
    printf("Hello %s\r\n", $name);
};

$greet('PHP');

I am getting this error:

Fatal error: Function name must be a string

On PHP Version 5.3.10-1ubuntu3.8 it is working as it should. Does anyone what is going on?

its because of eAccelerator and you should disable it

To turn off eAccelerator, make the following changes in your php.ini configuration:

eaccelerator.enable 0
eaccelerator.optimizer 0

or in .htaccess files

php_flag eaccelerator.enable 0
php_flag eaccelerator.optimizer 0
