bcompiler crash

Hi,
I've encountered a crash while using bcompiler (version 0.6). Here goes a 
backtrace:

I've narrowed offending code to this (in multiple files):

File: index.php
<?php
include_once('compiler.php');
include_file('config.php');

?>

File compiler.php: 
<?php
function include_file($file)
{
        static $compiler;
        static $ini;
        $fh = fopen($file.".phb", "w");
        bcompiler_write_header($fh);
        bcompiler_write_file($fh, $file);
        bcompiler_write_footer($fh);
        fclose($fh);

        include_once($file.".phb");
}

?>

File config.php:
<?php
include_file('exception.php');

?>

File exception.php:
<?php

class RuntimeException extends Exception
{
        public function __construct($message = NULL)
        {
                if (is_string($message)) {
                        $message = sprintf("Error: %s.", $message);
                } else {
                        $message = 'Unknown.';
                }

                parent::__construct($message);
        }
}

class InvalidParamException extends RuntimeException
{
        public function __construct()
        {
                parent::__construct('Invalid params.');
        }
}

?>
