Summary

0003959: PHP parsing errors

Description

In both resin 4.0.4 and 4.0.5 (and I think 4.0.0), there is a bug in the PHP rendering that either results in a StackOverflowError (4.0.0), or IllegalArgumentException. The stack trace is:

The PHP code that causes this is in WordPress 2.9.2, when attempting to save General Settings. The code that fails is wp_includes/plugin.php:336:

    do {
        foreach ( (array) current($wp_filter[$tag]) as $the_ )
            if ( !is_null($the_['function']) )
                call_user_func_array($the_['function'], array_slice($args, 0, (int) $the_['accepted_args']));

    } while ( next($wp_filter[$tag]) !== false );

It's actually the while clause that causes the failure, something in the !== comparison.
