[SOLVED] form_error() Fatal error: Only variables can be passed by reference

[eluser]shane_[/eluser]
I pushed an app out to another server running

PHP 5.2.11 with Suhosin-Patch 0.9.7

and form_error() is causing

Fatal error: Only variables can be passed by reference in [the view file]

It works fine on the dev server running

PHP 5.2.10-pl0-gentoo


Same result with 1.7.1 and 1.7.2

It was an issue with newer version of PHP and bootstrapping Drupal from within Codeigniter.
